A Journey Through Time: The History of Kidney Beans
Kidney beans, Phaseolus vulgaris, have a rich and intriguing history, dating back thousands of years. Their story begins in the Americas, where archaeological evidence points to their cultivation as early as 7,600 years ago in Mexico and Peru. Kidney beans were a staple crop for indigenous populations, often grown alongside maize and squash, providing a complete and balanced protein source.
The Columbian Exchange, beginning in the 16th century, marked a turning point in kidney beans’ journey. Spanish and Portuguese explorers introduced these beans to Europe, and from there, they spread rapidly across the globe, adapting to different climates and cultures. Their popularity grew with their ease of cultivation, storage and use in diverse culinary traditions. The beans’ distinctive kidney shape is how they got their name.
Mastering the Art of Kidney Bean Cookery
Knowing how to cook kidney beans properly is essential for unlocking their full potential. Here’s a breakdown of the key techniques:
-
Dried vs. Canned Kidney Beans: The most common way of buying kidney beans is dried. This involves soaking and simmering. Canned kidney beans are pre-cooked and ready to use, offering a convenient option for busy cooks.
-
Preparing Dried Kidney Beans: Soaking dried kidney beans is a crucial step. This process helps to reduce cooking time and improves digestibility by removing some of the sugars that can cause digestive issues. Soak dried beans overnight (or for at least 8 hours) in cold water, making sure the beans are well submerged. Before cooking, rinse the beans thoroughly.
-
Cooking Dried Kidney Beans: After soaking, drain the beans and place them in a large pot. Cover the beans with fresh water (or flavourful broth for added depth), and bring to a boil. Reduce the heat to a simmer, cover the pot, and cook for 1-2 hours, or until the beans are tender. Add salt towards the end of the cooking time. Adding salt too early can toughen the beans.
-
Using Canned Kidney Beans: Canned kidney beans are incredibly convenient, as they are ready to eat. Simply rinse them in a colander to remove excess sodium and the starchy liquid that surrounds them. Add the rinsed beans to your dishes during the last few minutes of cooking to heat them through, or use them cold in salads and other preparations.
-
Other Kidney Bean Cooking Methods:
- Grilling: Kidney beans are not typically grilled on their own, although they can be incorporated into veggie skewers, or bean burgers. Pre-cook the beans before grilling for a short time to warm them through and get some char.
- Baking: Kidney beans are perfect for baking in a casserole or baked beans. Combine the beans with other ingredients (sauce, vegetables, meat) in a baking dish. Bake covered for around 30-60 minutes, or until the dish is heated through. Remove the cover in the last 15 minutes to allow the top to brown slightly.
- Sautéing: Sautéing is ideal for canned kidney beans. Heat some oil in a pan, add the rinsed beans, and any flavourings (garlic, onions, spices). Sauté for a few minutes until heated through and slightly softened.
Prepping Your Ingredients:
- Green Bean Preparation: This is only relevant for string beans, not for the dried or canned variety. Trim the ends of the green beans using a knife or kitchen shears. They can be left whole, cut into smaller pieces or sliced.
- Other Cutting and Preparation: Kidney beans do not require peeling or mincing. Kidney beans are usually used whole, pureed (for dips) or roughly chopped.
Storage: Keeping Your Kidney Beans Fresh
Proper storage is essential for maintaining the quality and longevity of your kidney beans. Here’s how to store them:
- Dried Kidney Beans: Store dried kidney beans in an airtight container in a cool, dark, and dry place.
- Canned Kidney Beans: Store unopened cans of kidney beans in a cool, dry place.
- Cooked Kidney Beans: Store cooked kidney beans in an airtight container in the refrigerator. Cooked beans can also be frozen.
How long can you expect your kidney beans to last?
- Dried Kidney Beans: If stored properly, dried kidney beans can last for 1-2 years, or even longer. It’s a good idea to check them for any signs of spoilage, such as insect infestation or unusual odour.
- Canned Kidney Beans: Unopened, canned kidney beans generally have a shelf life of around 2-5 years. Check the ‘best by’ date on the can.
- Cooked Kidney Beans: Cooked kidney beans will last in the refrigerator for 3-5 days.
- Frozen Kidney Beans: Cooked kidney beans can be frozen for 2-3 months. Freeze them in a single layer on a baking sheet, then transfer to a freezer-safe bag or container.
