Soaking dried beans overnight speeds up the cooking. Always pick through them before soaking to remove any small stones or moldy beans. Cover them with cold water to 2 inches above the surface of the beans, and stir in 2 tablespoons of kosher salt per pound of beans before soaking. Drain and rinse before you start cooking.
