I just cooked mine in, I see no reason to use alcohol.
What I did was I took some really dry powdery bud a little over 3g (very mild) to 1/2 C coconut oil in a small crock pot and let cook for a long time. I did not strain my bud after, but I wish I did.
This is how I was told to make cannabis capsules (don't strain the bud, just capsule it), I figured this would be easy for food.
