    I’ve been lurking on the forums here for the last couple of weeks and the first thing I want to say is thanks! I have already discovered a wealth of information and valuable advice and I’m sure more is to come.

    Now, on to the details.

    I have made some edibles in the past, but only ever using traditional butter methods - and mostly without a great deal of success. I was very interested when I started reading about coconut oil and thought it’d be a great way to get some experience with reclaiming ABV.

    I have already seen a number of threads along similar lines, and I do apologise for inevitably rehashing points touched on before, however one thing I am often left wanting when reading of people’s adventures is specifics. I guess I’m a bit anal-retentive, but I really like to know every little step someone has taken to get to the final product. The more information you can provide, the more likely others are going to be able to reproduce your results.

    To that end, I thought people might like to know exactly how I made my coconut oil and fudge. So, here goes. . .

    Coconut Oil

    Ingredients

    Unrefined coconut oil - to a total of 100mL

    You can use refined coconut oil also, which differs from unrefined coconut oil in the following ways:

    Cost - the supermarket when I purchased my coconut oil sold the same amount of refined coconut oil by the same manufacturer for approximately 35% less. The main reason for this is that manufacturing unrefined oil is a more time consuming and cost intensive process

    Taste - refined coconut oil has been bleached and heat treated which removes the strong coconut taste and aroma. Because of this, refined coconut oil is a more flexible option for cooking a wide variety of dishes

    Composition - as the fat content of the oil is what the active compounds are extracted into it is lucky that the fat profile of both oils is practically identical, and either should results in similar strength results when used for extraction. The amount of the fatty acid lauric acid - which increases HDL or ‘good’ cholesterol - is also the same for unrefined and refined coconut oil. Unrefined oil, however, has a much greater concentration of phytonutrients which are effective as antioxidants.

    Refined coconut oil also has a higher smoking point, and is therefore a safer oil to use for high temperature cooking. The smoking point is the temperature at which a fat or oil starts to degrade and produce toxic byproducts. As we’re cooking with actives, keeping temperatures low is a major concern and the smoking point of unrefined oil (~ 350 fahrenheit / 177C) is safe for most uses.

    Finally, if you are going to use refined coconut oil, try and avoid those that have been partially hydrogenated as this will increase the trans fat content which acts to increase LDL - or ‘bad’ cholesterol.

    7.0g ABV

    The material used was ABV medium quality outdoor bud. The vast majority was vaped in a Pinnacle Pro on the lowest setting, which is approximately 370 fahrenheit or 188 celsius. There was also a small amount (less than 1.0g) of ABV from a Solo Arizer and MFLB.

    I ground 7.3g of ABV in a small food processor until it was quite fine, with some being powdered, resulting in 7.0g for extraction.

    2 teaspoon of soy lecithin granules

    Soy lecithin is an emulsifier, which assists with the absorption of fats during digestion. The theory is that it allows for the fats and oils (and therefore the active compounds) to be absorbed faster and more completely, resulting in a quicker onset and more effective overall dose. Even without this benefit, soy lecithin has also been shown to reduce LDL and inflammation in the body.

    Some people prefer powdered lecithin over granules, however I didn’t have any issues with the granules dissolving.

    1 teaspoon white vinegar and ½ teaspoon salt

    To be honest, I’m not up to scratch on the theory behind adding these to oil extractions, but anecdotal evidence suggests it helps getting the most out and I thought it couldn’t hurt.

    Method

    Approximately 100g of coconut oil was heated gently until completely melted. 1 teaspoon of lecithin, the vinegar and salt, and 7.0g of ground ABV were placed in the bottom of a pint sized mason jar and the oil added to a total of 100mL. The jar was then shaken for 5 minutes to ensure complete mixing.

    The mason jar was then placed in an electric slow-cooker and water added until the jar was half submerged. The slow-cooker was set to the ‘low’ setting*, and the mixture left for a period of 24 hours. During the first hour the jar was agitated once every fifteen minutes, then once an hour for 3 hours, and finally once two hours before completion.

    Once complete, the jar was removed from the slow-cooker and the oil allowed to cool until solid, ready for use.

    (NB Ideally the more agitation the better while heating, but I had to work and sleep during the 24 hours)

    * The temperature of the water was measured at 70C after reaching temperature

    Results

    The final cana-coconut oil was dirty brown in colour, and had a strong scent of coconut with mild hints of marijuana. After solidifying, a small amount of undissolved ABV remained visible in the jar.

    At this point I was excited to have made the oil with no problems (what can really go wrong with such a simple process?) but was still unconvinced it was going to be useful. I decided to make fudge as it’s a simple process, and if things did turn out poorly at least I hadn’t wasted a whole lot of time and energy. Below is the recipe for the maple chocolate fudge I made.

    Maple Chocolate Fudge

    Ingredients

    100mL cana-coconut oil

    80mL pure medium maple syrup

    ½ cup unsweetened cocoa

    ¼ cup caster sugar

    1 teaspoon vanilla essence

    a pinch of table salt

    Method

    The mason jar containing the oil was heated gently in water until the oil had completely melted. The warm mixture was then placed in a mixing bowl and the remaining ingredients added and folded through with a spatula. Once fully combined the batter was poured into small tupperware container (approximately 12cm square), allowed to cool to room temperature, then placed in the fridge.

    Results

    Once set, the fudge smelled strongly of chocolate and coconut. The scent of marijuana was present, but only very slightly. The total amount was divided into 7 serves (~28g of fudge, containing 1g of ABV).

    The fudge tasted mostly of chocolate and coconut - not unlike a chocolate crackle - with a hint of maple and marijuana. The texture was mostly smooth and a little grainy - probably due to the undissolved ABV and crystallised sugar. Overall, it was pretty tasty for regular fudge, and more than acceptable compared to a lot of edibles I’ve had in the past.

    And finally,

    The High

    Five of us had a dose each. One friend, who rarely uses marijuana, felt effects within the first half hour, and was well baked by an hour in - lasting a total of maybe four hours until he fell asleep.

    A second, who smokes regularly, felt noticeable effects within an hour lasting four to five hours.

    The final two friends and I, who are ‘heavy users’, noticed some effects within the first 30 minutes to an hour, with the peak arriving approximately two to three hours in.

    Personally, I found the onset to be relatively quick, and very gentle. I was by no stretch of the imagination blown away, but I was certainly high and hadn’t smoked or vaped a thing. Basic memory anomalies were the most obvious effect, with an otherwise clear head and comfortable body high. About four hours in I had half a bullet from a Pinnacle Pro and was noticeably more intoxicated than usual from so little vape. By six hours in I had been up for twenty hours, and was tired and ready for sleep. Lying in bed my thoughts were very lucid and sleep came quickly. I awoke eight hours later feeling rested and with minimal mental residual.

    So there you have it - my first experience making cana-coconut oil and a recipe for a nice way to eat it. Next time, I plan on making the dose one and a half to two times stronger for myself, but my first two friends said their dose a good level for them.

    I hope you’ve enjoyed my first post, and sorry it was so long! I’d love to hear any thoughts, suggestions and questions you guys have.

    Thanks.
    a couple questions:
    1. where does one get soy lecithin granules?
    2. does the maple syrup need to be real or will Mrs Butterworths work well? A fake maple syrup?
    3. what is "caster sugar"? Not familiar with that term.
    After I get more ABV I'm looking to try making some edibles and this one is interesting.
    Thanks

    #1 just google it (amazon/ebay), many natural/supplement joints would have it as well let your fingers do the walking if you want it locally. #2 I doubt it, just better flavor and a healthier source of sweetness.
    #3 just highlight the term, right click and do a web search; your google-fu is very weak!

    MinnBobber:

    1. Where I live in Australia you can find lecithin the health food isle of any major supermarket (same as un/refined coconut oil) - maybe worth a try?

    2. grokit is spot on - real maple syrup contains no additives. The sap from sugar maple is slightly concentrated and thats it. With fake maple there's a lot of refined sugars (like high fructose corn syrup or other fructose rich sweeteners). Fructose is metabolised in the liver and diets containing high amounts of fructose can lead to all sorts of health issues like liver damage, increase in LDL and uric acid in the blood and some studies suggest even cancer. On top of this, fructose doesn't make you feel as full as other sugars when ingested so you're more likely to over eat.

    With that being said, it's not like you're going to be eating fudge every day, and you're already adding sugar (sucrose = glucose + fructose joined) so its not 100% natural to begin with.

    It's a healthier choice if you feel like it - plus it tastes better!

    3. I had a quick search and it appears a lot of people on the internet aren't sure what caster sugar is. In Australia it's our standard cooking sugar - it's much finer than regular sugar but not powdered like icing sugar.

    Turned out a medium brown/green.
    Haven't tried it yet but it smells good.

    Sounds good - make sure to let us know how it goes! Any idea what you're going to use it in?

    I made another batch of oil with a friend on Sunday, this time using twice as much oil and 10.5g of leaf and small buds. We used as the same amount as in the OP for the vinegar, salt and lecithin. In retrospect the amounts were probably a bit of overkill for so little oil - but better safe than sorry. Might try and halve the values next time I make 100ml.

    Did you use flowers Breathemetal? Just wonderong about the colour of your oil - as I said, mine was 100% brown. If it was just ABV maybe it wasn't vaped as hot/long.

    I didnt see what the second batch turned out like, my friend picked it up while I was at work. When it was on the slow cooker it looked pretty dark green / brown. I'll ask for a pic once he has strained it. Unfortunately there was a LOT more undissolved material left using bud - too much to eat without noticing.

    Interesting - do you know what temp on average it was vaped at?

    Also, how much of the other ingredients did you use?

    Eyeballed it.
    It was vaped through my ssv, pretty hot. I like higher temps. Dark brown abv.

    Is there a strong odor while the oil is cooking? I live in a house with non-vapers; they don't even know I do. But, I want a plan for when I have enough ABV. I just need to be stealthy.
    Any tips?

    There was minimal odor for me. I think having everything contained in the jar helps

    @momothelemur

    The first run with the ABV had very little odour - not enough to make the room smell of material.

    The two subsequent runs I've done with flower have had a subtle smell while mixing. Once sealed in the jars and the slow cooker you couldn't smell anything.

    So i have a little over 120ml of infused oil.
    just nuked it to get it to liquid state again. it was in the fridge for a few days.
    today is my off day so im going to use this day as a test to see if i want to make it again (stronger, weaker, less coconut oil, etc)

    Just dumped it all into a bowl of fried ice cream. Ill report back if anything happens. Im doubting it will do anything as edibles and me never really get along.

    How'd it go? Did the whole 20g end up in that 120mL?

    Hello all. I'm shortly moving out of my house and into a flat with my girlfriend into Uni halls. This means that I can experiment with the slow coconut infusion method and hearing that it doesn't smell much is a huge relief. However, I don't think I'll have access to a slow cooker. does anyone have any other suggestions for keeping your mason jar warm? I live in the UK so maybe just rest on a radiator? Anyhow, keep posting and thank you @billy for your post. Really great to have some specifics!

    As ABV is already decarbed the heating in the slow cooker is more to ensure complete extraction into the oil.

    If placing the jar on top of a radiator will keep it above 40C (the melting point of the oil) it should work fine. You could always leave it there longer if you were worried, but the in reality the 24 hours in the slow cooker was one of those "better safe than sorry" decisions.

    Another thing to consider is that the heating from the radiator will be mostly from one direction - versus the near uniform hear provided by the slow cooker - so shaking more often might be necessary.

    Ahh okay. That a shed some light on things, thank you. In regards to the direction of heat:

    Please correct me if my theory is incorrect. If I were to place half the bottom of the mason jar on the radiator then surely the convection currents inside the oil would 'self mix' to some extent. Therefore this would reduce the issue of needing an all round heat source. I agree about the liquidation point but with something like oil, surely the point it becomes liquid is a subjective thing? Any who, arguing the point about liquid is silly haha. I might just wait till I have enough abv to even use and then give it a go. Maybe i will just have to brew mine for longer. I'm a patient kind of guy, I'm sure I'll survive ;).

    No sweat.

    A side note - the melting temp of coconut oil is 24C not 40C. I'm not sure where I pulled the original value from.

    In relation to mixing - you would certainly have some mixing take place based on the convection of the oil. With that being said, with the temperature applied being quite low and the viscosity of the oil high I don't believe you would achieve any reasonable amount of mixing during a 24 hour period. You certainly would not obtain an even temperature throughout the mix.

    I'm not an expert in the matter, but I do have majors in chemistry and physics, so have a reasonable backing in relation. I have always been taught that if you can't see mixing occuring then it's not happening to an extent to be very beneficial.

    As for the oil liquifying - the melting point of a material does depend on a number of factors - but in the given situation most can be discounted. For example, pressure will affect the melting point but doesn't fluxtuate enough in our circumstance to be considered. The melting point of a pure compound will be over a very small range (generally less than a few degrees celcius). As coconut oil is a bit more complex than a single compound one would expect the melting range to be slightly extended, but if you are to evenly heat the entire mixture to 24C for a period I can guarantee it will all be melted.

    The melting point of a substance is a physical property, determined primarily by the size and shape of the molecules present and the intermolecular forces between them. While coconut oil composition does vary, it's not enough to affect such inaccurate measurements using household equipment.

    EDIT

    I realised you were probably referring to what each of us would define as liquid rather than the process of melting itself.

    Coconut oil is a solid at room temperature (most of the time). At higher than a given temperature the solid material will experience a phase change to liquid. This process won't be instant, but it will happen at a reliable temperature. As the oil heats further it will become less viscous, but that isn't what I was referring to.

    *applaud*

    Very good my friend. I also studied chemistry at college. Although you seem to have a much better grasp than I ever did. I'm new to this forum and didn't realise it was acceptable to post in such scientific ways. I shall adapt haha.

    I agree with your point as to the mixing via convection. Viscosity was always a strange topic for me. I understood the principles behind it, it just always seemed to pass me by. Back on topic.

    40C did make me chuckle I must admit. I had heard of coconut oil having a low liquidation point, with 40 being fairly low compaired to some organic compositions, but not that high hehe.

    How many doses have you had sir?:ko:

    Haha, I'm sure you're underestimating yourself! I really like to know how things work quite specifically, I guess it leads me to over-explaining things sometimes.

    Simply put, as you heat a volume of liquid it becomes less viscous.

    40C honestly just popped into my head - I have no idea why :p

    Embarrassingly enough, I was sober when I got the temp wrong. I was on my lunch break at work. Once I got home, had a load from my vape and was reading over the forums was when I realised.
