How to Rehydrate Kidney Beans

If you purchase dried kidney beans, instead of canned beans, they will need rehydration before cooking. There are a number of ways in which to rehydrate dried kidney beans. The easiest method will take about 8 hours. Quicker hydration methods take between 1 and 3 hours to complete. If you prefer a gas-free bean, use the gas-free soak hydration method.
