Dried beans are frugal, a wonderful source of protein, and ultimately are more healthy/safe and tastier than those from a can. When I'm in a hurry, I still am known to use canned beans, but I love dried beans! Really though, preparing beans isn't that hard.
1) Wash your beans and pick through them to ensure there are no little stones or bad beans present. Then cover them with cold water. Six times the amount of water to beans is the best because the beans will rehydrate to almost double their size. Let the beans and water stand overnight. Then drain and rinse.
2) Place beans in an appropriate sized saucepan and cover by at least 1/2" with cold water. Bring them to a boil. Then reduce heat a let simmer covered for about 45 min or until tender. Time will vary depending on the size and type of bean you are using. If the water goes below the top level of the beans, simply add more water and cover again.
3) While the beans are simmering, check occasionally to skim away any impurities that float to the surface. Drain your beans and rinse again before using them in your favorite bean dish.
**All that rinsing gets rid of the starchlike compounds that cause the flatulence later. Or at least reduces the amount of flatulence anyway. :o)
