Cooking Cooking... for beginners!?

[kckool]

So, I was talking to my friend, and he has never eaten cannabis before. He has smoked it for a few years now and enjoys the high, but he's interested in cooking. However, he is on a college budget and isn't a heavy smoker, so he does not own tons of weed, certainly nowhere near an ounce, just a few dime bags. He was wondering what the minimum amount of weed needed would be to achieve the proper effects of eating, and what the best method would be?
