First off, you want to go to the store and get some Ramen Noodles. They cost 30 cents a pack so it shouldn't be a strain on any budget.
When you get ready to cook, bring water in a pot to a medium boil. You don't want it spraying all over the place. Also: Don't use too much water! Two cups will probably be sufficient for now, and if you need more then just add more in later. Take the amount of weed you want to cook with (usually use slightly more than the amount needed to get high by smoking). Chop up the weed as fine as you can get it.
You will also need butter of course. A rule I use that seems to work every time is to get an amount of butter that looks about the same size as the amount of weed you have. Then, get more butter (about half as much as you have now) and add it to your butter pile. So you will probably have two piles, one of weed and one of butter. Add both to the boiling broth. You might also consider adding in other spices like oregano, garlic, or other greenish spices in case people get nosey; you could just tell them it's oregano or whatever. Plus the spices will mask any smell that's produced by cooking.
You'll want to boil it for at least 20 minutes, but the longer you can the better. If you have time to boil for a while, boil the weed until it's totally brown. If it's mostly brown though, then you should be alright. Now plop the ramen noodles into the boiling water and stir and cook for about 5 minutes. Pour out all contents into a bowl (including the weed, don't strain it out you might as well eat it) and add in as much of the Ramen seasoning as you'd like.
It actually tastes quite good, although a tad buttery. The Ramen Flavoring does a good job of covering up any nasty weed-tasting gunk in the soup. Just eat it all, sit back and wait. In about 1-2 hours you will be *quite* messed up, depending on how much weed you used. I usually use about 2 bowls worth of kind bud, and I get pretty far out there.
This is a great recipe for a few reasons:
One, it doesn't cost much at all.
Two, cooking with such a small amount doesn't really stink up the house so you can do it if your parents are around.
Three, it gets you pretty damn stoned.
