Bitter Lupin Beans: Soaking Guide

To soak bitter lupin beans, also known as “termis al mer” in Arabic, follow these steps:

1. Selecting and Cleaning: Choose high-quality bitter lupin beans from a reliable source. Rinse the beans thoroughly under cold water to remove any dirt or debris.

2. Soaking Process: Place the cleaned bitter lupin beans in a large bowl or container. Add enough cold water to completely submerge the beans, ensuring there’s room for expansion. The ratio of water to beans should be about 3:1. Soak the beans for at least 24 hours, preferably changing the water every 8 hours or so. This helps reduce the bitterness and makes the beans more palatable.

3. Testing for Readiness: After soaking, taste a bean to check for bitterness. If it’s still too bitter for your liking, continue soaking and changing the water until the bitterness reduces to an acceptable level. This process can take up to 3 days depending on the beans and your desired taste.

4. Draining and Rinsing: Once the bitterness is at a desired level, drain the soaked beans and rinse them thoroughly under cold water. This step helps remove any remaining bitterness and excess salt from the soaking water.

5. Optional Boiling: Some recipes recommend boiling the soaked bitter lupin beans in fresh water for about 15-20 minutes to further reduce bitterness. However, this step is optional and depends on personal preference.

6. Seasoning: After draining and optional boiling, season the soaked bitter lupin beans according to your preference. You can add salt, olive oil, lemon juice, garlic, or other spices and herbs to enhance the flavor.

7. Storage: Store the soaked and seasoned bitter lupin beans in an airtight container in the refrigerator. They can last for several days when properly stored.

8. Consumption: Enjoy the soaked bitter lupin beans as a snack, appetizer, or as part of salads, stews, or other dishes. They are a nutritious and flavorful addition to many recipes.

It’s important to note that bitter lupin beans contain alkaloids that can be harmful if consumed in large quantities without proper soaking and preparation. Always follow these soaking and cooking guidelines to ensure safe consumption.
