Firecracker?

Any kind of oil/butter will do if it has a high fat content man

 

No worries man people just use Coconut oil because it doesn't taste as bad as normal oil it's just taste preference really, I've made them with coconut oil & normal oil before you can't really tell the difference man

 

This is very easy, and there is no need for any oil.
Peanut butter is 50% peanut oil, and the non-oil parts furnish a good structure to keep the herb well dispersed for good digestion. Adding oil to it, will just make it too gooey.
I've made literally hundreds of these things using home made nutella and keebler club crackers. My testing shows they are just as strong, and probably stronger, than anything else made with the same amount of herb.
Here's the simplest, equal to the most potent method:
(1) Decarb @ 240 F for 40 min using a verifying thermometer
(2) Grind to a fine powder
(3) Mix into nut butter and use. Each gram of 15% herb used will contribute 150 mg thc.
There is no need, and no advantage for doing the 2-stage decarb that most firecracker recipes call for.
I keep bowls of this stuff sitting around.

 

You're right to ask questions PRIOR to making firecrackers. Typically someone writes in that they didn't work and asking why when it's too late. Don't forget to decarb- 240F for 40 minutes, even if you're only using a gram- decarb. Bkarnaze and Brewsnweed gave good advice. Do what they said and enjoy!
