You can bake directly with kief!
Or, I've also heard of pre-baking the plant material. (this would be important)
That is, put material in a ceramic/glass(as I recall) container and bake according to temp and time. I've seen higher temp quick-bakes and lower-temp long bakes. Never done it. So I'll leave it at that. You end up with slightly cooked smelling weed... not sure what you'll do with that!
I suppose pre-baked kief or even shake(gag) might work in a smoothy. Perhaps a coffee grinder first....
You can eat fan leaves raw, they're a leafy green, and as such are quite nutritious. Pre-baked to activate THC might even make get high... don't know about taste! Perhaps in a pasta sauce, tossed with noodles garlic and olive oil.
Allez cuisine!
