Cooking with Dry Beans

How do I sort and clean dry beans?

Spread beans on a light tray and look through them. Remove stones, dirt clods, shriveled or cracked beans and anything that is not a bean. Home-grown beans may also contain bits of pod. Rinse in cold water and drain.

Throw out beans with holes, which can come from insects, and any that are moldy or smell musty. If you find many damaged beans, check how they were dried and where they are stored.

Home-grown beans benefit from an extra look, because they may include immature, discolored or damaged seeds. A bright light and a plain tray make the faults easy to see.

Do I really need to soak beans?

Soaking shortens cooking and helps beans cook more evenly, but it is not required. Many cooks soak overnight in plenty of cold water and then discard the soaking water. Others skip soaking and simply allow more cooking time. The choice depends on how much time you have and how the beans respond.

Some people find that discarding the soak water makes beans easier to digest. If beans cause discomfort for you, a doctor or dietitian can offer guidance that fits your health, which a general guide cannot.

• Use a generous amount of water for soaking
• Keep soaking beans cool or refrigerated in warm weather
• Drain and rinse before cooking
• Cook unsoaked beans longer, checking often

Why are my beans still hard after hours of cooking?

Old beans are the most common cause. Beans stored for a long time, or kept somewhere warm and humid, can resist softening no matter how long they simmer. Hard water and adding acidic ingredients such as tomatoes, vinegar or citrus early in cooking can also slow softening.

Keep acid and salt-heavy ingredients for late in the pot unless your recipe says otherwise. If beans never soften, they may be too old, and they are better used ground or in a long-cooked dish than thrown away.

Altitude and water minerals can both slow cooking. If your beans consistently struggle, ask a local extension agent whether hard water or elevation might be part of the cause.

Are any beans unsafe if undercooked?

Yes. Some beans, red kidney beans in particular, contain a natural compound that can cause illness if the beans are not cooked thoroughly. Slow cookers that do not reach a high enough temperature have been named as a concern in food safety guidance.

Follow cooking directions from a trusted source such as USDA, an extension office or the seed company that supplied your beans, and cook beans until they are completely tender. If someone becomes ill after eating beans, contact a doctor or poison control.

Beans that have been picked over, soaked and simmered gently tend to keep their skins whole. A hard, rolling boil can burst them, so keep the heat low once the pot comes up to a simmer.

How can I use a pot of cooked beans through the week?

Cook a big batch and use it several ways. Serve some plain with greens and cornbread, mash some for filling, add some to soup, and chill or freeze the rest in meal-size portions with some cooking liquid. Cool cooked beans quickly and refrigerate them promptly instead of leaving them on the stove.

Cooked beans freeze well in freezer-rated containers. Leave room for expansion and label with the date. Do not try to can beans without a current tested pressure-canning recipe, since beans are a low-acid food.

How should I store dry beans?

Keep dry beans in airtight containers in a cool, dry, dark place. Heat, light and humidity shorten shelf life and make beans harder to cook. Insects can be a problem for home-grown beans, so check with your extension office about handling harvested beans before storage.

Mark the harvest year on every container. Use older beans first, and plan to cook the oldest ones with the longest simmer and the most patience.

A pest-proof container with a tight lid is better than a paper sack. Check the beans every month or so, and if you find insects, ask your extension office how to treat the beans safely.
