Tips for Preparing Lima Beans
Before washing dried lima beans, spread them out on a light colored plate or cooking surface to check for and remove small stones, debris or damaged beans. After this process, place the beans in a strainer, rinsing them thoroughly under cool running water.
To shorten their cooking time and make them easier to digest, lima beans should be presoaked (presoaking has been found to reduce the raffinose-type oligosaccharides, sugars associated with causing flatulence.) There are two basic methods for presoaking. For each you should start by placing the beans in a saucepan and adding two to three cups of water per cup of beans.
The first method is to boil the beans for two minutes, take the pan off the heat, cover and allow to stand for two hours. The alternative method is to simply soak the beans in water for eight hours or overnight, placing the pan in the refrigerator so that the beans will not ferment. Before cooking the beans, regardless of method, drain the soaking liquid and rinse the beans with clean water.
The Healthiest Way of Cooking Lima Beans
To cook lima beans, place them in a pot and add three cups of fresh water or broth for each cup of dried beans. The liquid should be about one to two inches above the top of the beans. Bring the beans to a boil and then reduce to a simmer, partially covering the pot. Lima beans generally take about 45 minutes to become tender when cooking this way. Lima beans may produce a lot of foam during cooking. Simply skim any foam off during the first half hour or so of the simmering process. Because of the foam limas often produce, it is recommended to avoid cooking them in a pressure cooker.
Do not add any seasonings that are salty or acidic until after the beans have been cooked since adding them earlier will make the beans tough and greatly increase the cooking time.
While uncooked lima beans contain compounds that can inhibit a digestive enzyme and cause red blood cells to clump together, soaking and cooking the beans renders these compounds harmless. Therefore, it is important to always eat soaked and cooked beans and not to use them uncooked by, for example, grinding dried beans into flour.
