Even then you do not have to rinse beans if you're going to soak them. Any field dust will be removed and discarded with the soak water. If you cook the beans without soaking, rinse them after sorting. Soaking Soaking is not an essential step in bean preparation. The purpose of soaking is to begin rehydration before cooking, thereby reducing cooking time.
Unsoaked beans take longer to cook and require more attention so they won t cook dry.
During soaking, beans make up their lost water, increasing up to twice their dried size. Enough water must be used to keep the beans covered while soaking . Once rehydrated, beans cook in 1 to 3 hours, depending on the type of bean. Both work equally well and differ only in the amount of time required to rehydrate the beans. Choose the one which best suits your time and schedule.
