Instead of masking it, remove it !
I've got the solution for you, I don't liked the taste of the edibles either until I came up with that :
You gently boil your AVB in water, for at least 24 hours, changing the water 4 or 5 times (till it's coming clear), separating the stuff from the water with that :
The first couple waters comes green/dark brown, all that shit won't end in your final product
no loss of thc since its not solvable in water.
Then you press it in a non colored clean cotton (not washed with chemicals) tissue to remove the water soaked in the material and let it dry by spreading it on a large, clean, flat surface. (i used a mirror that i cleaned with white vinegar, you don't want to contaminate that stuff you will eat)
I placed a small electric heater near it to accelerate the process of drying
When fully dry, you crush it to make fine powder to maximize extraction.
All the bad taste has been removed !
It is now ready to be putted it in your oil, your alcohol, butter or your glycerin, whatever you want
I prefer cold extraction, its less complicated and you get a nice final product, the efficiency is at least as good if you have the time.
I did it with some organic purified cooking oil, letting it sit with the AVB in a jar for a bunch of months, shaking it regularly. filtrate (cotton tissue..). the oil was very powerful and the taste was neutral, i can drink it easy, just by puttin it on top of some fruit juice. I used it every day for a 15 day vacation, no weird stomach issues, common with edibles. The color of the oil was not dark at all, more like greenish yellow, looking and smelling just like some kind of thick olive oil. Very easy to stash, nobody would notice it !
Next time i will try with glycerin to make a really concentrated product that will end up in a spray.
I may have to use alcohol 95° for the extraction, then evaporating the excess, then mixing it with glycerin.
edit : just seen longbones post, we use the same kind of method but he don't heat the water, heating the water accelerate and enhance the process without causing thc loss since AVB already have been heated by far more higher temperatures.
It is totally working, so use it !
