You can also do a "rapid" cooking method. Put beans in a large pot, cover with at least 2 inches of water. Bring to a boil, boil for 2 minutes, then turn off the heat and let sit for an hour. Drain and rinse a couple times.
I did this, just this morning. I needed black beans for a crockpot recipe, and didn't have any cans of black beans. A pound made ~6 cups of cooked beans--I used 2 cups in my recipe, and threw the rest in the freezer.
I will admit, I usually buy canned beans because it's easier, but really, dried beans are pretty simple. Or maybe I just have that Bean Thumb thing going on.
