Soaked rajma (kidney beans) should be stored in the refrigerator for no more than 24-48 hours. Change the water every 12 hours to prevent fermentation.
Soaking rajma is an essential step to reduce cooking time and improve digestibility. However, soaked beans are susceptible to bacterial growth and fermentation if not stored properly. After soaking, drain the rajma and rinse them thoroughly. Place the soaked rajma in a clean container, cover them with fresh, cold water, and store them in the refrigerator. It's crucial to change the water every 12 hours to minimize the risk of spoilage. Storing them beyond 48 hours is not recommended, as the risk of bacterial contamination significantly increases, potentially leading to foodborne illnesses. If you are not planning to cook the rajma within 48 hours, it is best to freeze them.
If you need to store soaked rajma for longer than 48 hours, consider freezing them. Drain the soaked rajma, spread them in a single layer on a baking sheet, and freeze until solid. Then, transfer them to a freezer-safe bag or container. Frozen soaked rajma can be stored for up to 2-3 months.
