Eat it! I have some crappy beer in our frig leftover from a get-together of some sort. No, I didn't plan to serve it to guests to be an ass, my friends actually like crappy beer. LOL. Aside from their poor taste in alcohol, they are actually OK people. But, what is a girl to do with a six pack of this nasty stuff?
Make beer bread! I found the easiest beer bread ever recipe (link below). Super simple, throw everything in and mix, bake and eat. Best use of bad beer I've ever found.

Don't forget to sift your flour! It makes it more moist and a better loaf of bread.
