Firecracker sans oven??

I have become quite interested in Firecrackers. I don't have an oven just a really crappy stove. Do you think if I had two slices of bread (thick or slim??) with peanut butter and hash in between could I just wrap that in aluminum foil and cook it slowly via stove top on like medium heat, and still get the same effect? This question might sound dumb but I have never cooked with MJ before.

I am absolutely not an expert when it comes to cooking marijuana but as a damn fine cook, your theory of cooking on top of the stove seems like a good one. I read recently to cook marijuana for at least 15 for the full potency to come up. Good Luck!
