Well, actually, I was kind of thinking about trying this with a salmon steak I have. You can use a slow-cooker as a baker, and since salmon is a fairly fatty fish....

What I'm planning on doing is putting the fish at the bottom of the slowcooker, skin side down, rubbing a bit of crushed up weed onto the top side, drizzling some olive oil over the weed and then cooking it on low for 3-4 hours. Theoretically, the processes occuring while the weed cooks on top of and into the salmon would be the same as making weedbutter, but with the added effect of flavoring the salmon. Since I'm a lightweight for pot, I'd probably not use that much weed. Maybe 1/3 gram of chronic. 1/2 a gram if I get nervous.

I figure the portion of salmon I eat will balance out my being a lightweight. Could also theoretically collect all the oil from the bottom of the cooker into a small container in the fridge for adding a bit of THC to other foods.
