Two Ways to Soak Beans to Reduce Gas UncategorizedBean Bulletin, Cooking, Tips While not every recipe calls for soaking beans before cooking them, if beans give you gas, soaking can help. Soaking overnight and then discarding the soaking water leaches out sugars in beans that are responsible for gas production. But if you don’t have time for a traditional overnight soak, a quick soak is just as beneficial. Rinse the beans and then place them in a pot with three cups of water for each cup of dried beans. Bring to a boil and boil for two to three minutes. Remove the pot from the heat, cover and let stand for one hour. Drain the water, add fresh water and cook.
