I have one more batch to try, and that's going to be sort of a mixture of both and this is how I plan on doing it........
Important thing to note....oil is used for boxed brownie mixes, butter is used for brownies made from scratch.
So oil brownies....
1) Your favorite boxed brownie mix.
2) usually 1/2 cup of oil, but whatever the box calls for. Actually if the box calls for 1/2 cup, I would go ahead and start with 3/4's cup, you lose some in the process.
3) Ganja...I know, how much? Right? I would say for a 1/2 cup of oil at the finish you'll want about 7-10 grams of your buds. Not much at all, but if you want to see jesus you can definitely up this #, but hold on tight. If you use your trimmings and/or shake, go for a full ounce, it really is much weaker than buds are.
Your going to start out by pouring the oil into a jar (just like the jars for curing) and place that jar inside a pot of hot water. Making sort of a double - boiler. Get the water to where it just boils and then back it down a notch and add all the ganja. Let it simmer in there stirring occasionally for about 3-4 hours.
Strain it using a strainer and cheesecloth. The cheesecloth and how much to use is really kind of an experience thing. I used to use too large of a sheet and it would soak up all my oil! Now I strain through about two layers of cheesecloth and try to use as little as possible. But you have to get that oil as clean as possible, so do what you gotta do.
You're going to pour the hot mixture into yet another jar, through the strainer and cheesecloth and pour all of the plant material into the cheesecloth and hold it like a diaper. You might want to wear rubber gloves for the next part...squeeze all of the oil out of the cheesecloth into the jar.
Now just go cook your brownies with the oil.
If you don't want it to take 3-4 hours (which I didn't) you can put the oil into a pan on the stove, heat the oil and add the ganja, but you again have to make sure it's not hot enough to be "boiling". If it's boiling it will turn brown and burn all your THC off. That's why I like the double-boiler, but it can be done the other way...just understand that hotter CERTAINLY isn't better. That way needs about 40 minutes, then the rest is the same.
That's going to make about 12 - 16 brownies depending on how you cut them. I ate two brownies and got good and fucked up. My homie ate 8....he was just passed out.
So experiment with it, enjoy it and hit me up if you want me to write it out bettter, I'm just rambling without any kind of organization...haha.
