Beans that have been cooked at a high temperature are also harder to digest. A heavy duty pot provides the best results for cooking beans. The lid should be tight fitting to retain the moisture. Microwaves - I do not advise using a microwave to cook beans. Slowly simmered beans provide the best results.
Microwaves are great for reheating bean dishes.
Pressure Cookers - Cooking beans in one of the newer pressure cookers is both safe and much faster than with a conventional pot or slow cooker. Using this method also retains more of the nutritional value found in our food. Never fill a pressure cooker above halfway. Always follow the instructions in the manual. Because it is hard to determine exactly how long it takes, check for doneness a few minutes before the beans are supposed to be done.
