Flameon, the only problem with using clarified butter in a recipe that calls for the normal stuff, is that you'll add WAY too much oil and not enough water (since butter contains some water and proteins and is not 100% oil)

The best way to cook with cannabis is to first select a recipe that calls for oil. Canola, corn, sunflower, olive, it doesn't matter. As long as the recipe itself calls for straight up oil. Unfortunately this limits you a bit, as most (bad for you) baked treats involve butter. Box-mix of brownies calls for oil, which is why brownies are perfect to go hand-in-hand with cannabis

Once you have your oil-based recipe, you want to put about 2 cups of water into a medium pot (giggle), and float on top of that the exact amount of oil you need in the recipe. Bring to a boil and add your finely ground cannabis. Cover and let simmer for a couple hours, stirring occasionally and adding water if the level ever gets low. Notice that the oil turns green, while the water turns brown. This is a GOOD THING. The boiling water is essentially 'bong water' if you'll excuse the term, so we want to get rid of it. Using a turkey baster, carefully extract the water from underneath the oil layer. It's OK to leave a little water behind in the interest of keeping all the oil. Once you've removed the water, you should have exactly enough oil to add to your recipe, and it probably has a lot of extracted plant material floating in it. Personally I think it adds to the texture of the product (if you grind it fine enough and boil for ~5 hours, it has a pleasant toothsomeness, and the water took out all the nasty flavours), so I just add the oil plus plant matter to the brownies. Follow the instructions on the box (1 egg, etc), but bake at around 30-50° lower than recommended (like, 275 instead of 325) to limit the vaporization of THC. Check frequently while baking so you don't over-bake it, remember that brownies look underdone when they are ready.

Eat on an empty stomach for full effect, and enjoy! My recipe doesn't add extra salt like cannabutter does, and the brownie texture with a small amount of plant matter is absolutely delicious if you throw in some walnuts and choc chips to supplement the recipe a little. If you use enough weed, it's not too bad for you, because a single brownie (of a dozen batch) should get you flying out of your mind. Honestly, weed goes incredibly well with boxed brownie mix. It's a match made in culinary stoner heaven My suggestion is to save the scratch-made treats for non-cannabis use, because it's nearly impossible to actually make a suitable THC-impregnated butter replacement, only oil.

If you're really set on adding THC to something that doesn't call for oil, or must be heated above 300°F, I suggest making 10x strength cannabis oil. That is, boil more weed with less oil, so you end up with like 1/4 cup of ultra-high-potency oil. Then you can just add a tablespoon to whatever food you want. You could even put it in a dispenser bottle and take it to a restaurant and add a splash to your meal!
