Could you post a pic of your perfectly-packed bowl? I pack it pretty tightly, so shaking doesn't do anything usually.
If I knew how to post pic I would. It's weird on here right?
Real coarse grind, DONT' Pack Tight, even slightly below rim so you can shake a little, not stir. Remember, you're James Bond, you need it shaken not stirred. Yes!
I will figure out how to post pic tomorrow but the words are prolly more helpful.
Reggie, pack tight= little or no airflow= no convection magic= no medication delivery
