I, in no way, encourage you to make these - but if you find yourself in a situation where you are in the process of making pot brownies, please please please use this lone tip.
You see this guy?
Magic Bullet
He's your best friend in the world for this act. You know how people use those tiny little grinders? THROW THAT SHIT AWAY! If you're making these brownies, you MUST grind it up in the Magic Bullet. After it's blended in here, you will see more crystals ground up than you ever thought possible. It's insane. I wish they could somehow include this tip in the complimentary booklet of recipes or something. Maybe someday they will, they definitely should.
Anyway, YOU'RE WELCOME.
