I know its hard, but just give it two or three days, then you'll be able to pinch a bit off the ends and soon more and more, but those stems won't burn and you'll never get rid of that shitty taste until its fully dry
Take a toilet paper roll or papaer towel roll. (not the whole roll just the brown part after all the paper is gone) put a few buds in it. stuff a few pieces of tissue at both ends and give it 2 or 3 days. you should end up with a smokeable product!
Good Luck!
P.S NEVER EVER EVVVVVVVVER cook your buds! Unless you're cookin em to make your lungs dirty.....10-4?
