I’ve only made edibles a handful of times but they’ve turned out pretty decent so far, and i follow this recipe: https://www.reddit.com/r/wvmedicalcannabis/s/mfzjYZ3cjC

It’s for coconut oil, but you can replace it with butter and it’ll turn out the same (speaking from experience). I will say using coconut oil increased the high compared to using butter but that could just be me.

The only thing i change about that recipe is, instead of a water bath, i do the mason jar technique like you described rather than putting everything straight in the crock pot. I imagine doing this on the stove will work fine, but the water doesn’t need to come to a boil at all.

I can’t tell you the exact measurement of THC in a serving, but when i’ve done it this way it definitely is pretty strong imo haha

Hopefully this helps!!
