I went on a bean soaking binge this past weekend, and the amount of scum that came to the top of the large pot of soaking kidney beans was so huge, I thought it deserved its own blog post. Soaking beans for many hours before cooking them produces a lot of scum which is course, is rinsed and drained away when the soaking is complete.
What is all that scum anyway? Anti-nutrients, that’s what! And those anti-nutrients such as phytic acid, lectins, and enzyme inhibitors are going to be in your gut causing you gas, heartburn, reflux, and whatever other digestive ills beset you when you eat something that isn’t particularly digestible unless you soak your beans before cooking them. Traditional cultures took great care to prepare their legumes with a long soak before cooking to enhance digestibility and nutrient absorption.
I love Mexican food but really try to avoid Mexican restaurants for this reason .. they don’t soak their beans before cooking them! After a meal at a Mexican restaurant, I will typically feel very bloated. Eating the same meal prepared at home where I soaked the beans properly before cooking results in no digestive upset whatsoever.
Take the Soaked Beans Challenge!
If you think unsoaked beans don’t cause you any trouble .. take this challenge. Soak beans next time before cooking and notice the difference in your stomach after eating. You may think that the unsoaked beans don’t cause you any trouble, but you just may find that soaked beans are infinitely more filling and that you eat less and enjoy the meal more as a result!
Traditional peoples were very wise in the preparation of their foods. They not only selected nutritious foods but they prepared them for maximum digestibility and nutrition. What good is eating nutritious legumes if the body is so whacked by the anti-nutrients that it can’t very easily extract and digest the nutrition?
So, the next time you make your beans, make sure you soak them first!
I soak large pots of various types of beans every month or so and then cook them – freezing for easy, quick meals when beans are required like homemade chili.
**If you absolutely do not have time to do this, at least buy pre-soaked legumes and beans packed in glass jars. Your digestion will thank you!
How To Soak Beans Properly
If you’ve never soaked beans before, it’s so easy. It’s a very similar process to soaking nuts and seeds.
Kidney shaped beans
For kidney shaped beans and dried/split peas, put a pinch of baking soda and enough water to cover in a large pot and soak uncovered for 12-24 hours. Drain, rinse and cook as usual.
Examples of kidney-shaped beans include:
- Red kidney beans
- White kidney beans (cannellini beans)
- Pinto beans
- Anasazi beans
- Black-eyed beans (black-eyed peas)
- Great Northern beans
- Lima beans
Non-kidney shaped beans (and other legumes)
For more oval-shaped beans and other legumes, soak for 12-24 hours in filtered water to cover plus 1 tablespoon of cider vinegar or lemon juice for every cup of dried beans/legumes used. A homemade apple cider vinegar recipe or store-bought are both fine (make sure the ACV is packed in glass). Liquid whey from yogurt, kefir or clabbered milk may also be used. Drain, rinse and cook as usual.
Examples of non-kidney shaped beans include:
- Black beans (turtle beans)
- Navy beans
- Fava beans
- Adzuki beans
For maximum digestibility, it is best to rinse and refresh the filtered water and baking soda or the acidic medium once or twice during the soaking period. If you forget, no worries.
I try to always soak beans for the full 24 hours instead of just overnight. Sometimes if I get busy, I might even soak them 36 hours, but this is risky as they can get moldy sometimes if you go over 24 hours. Best to stay between 12-24 hours particularly during summer months.
After soaking, be sure to thoroughly drain and rinse the beans until all the scum is washed away. Fill the pot with fresh filtered water, bring to a boil, and skim away any additional foam that may come to the top at the start of the boil. Turn down the heat to a simmer, add 4 crushed garlic cloves, and cook until the beans are soft (about 4 hours).
Drain beans and add to your favorite dish or let cool and freeze in large freezer bags for quick meals at a later date!
Bye-bye Bean-o! You won’t be needing it or any other over the counter gas meds again after learning to soak beans before cooking!
Using the Soaking or Cooking Water
Some alternative cooking circles advocate using the soaking or bean cooking water. Unfortunately, neither of these practices is traditional. Using the cooked bean water or aquafaba is actually a dangerous practice. See the linked article for reasons to avoid this modern food especially during pregnancy!
DIY How-to Video: Soaking Beans / Legumes
This article plus video on soaking lentils provide additional information specifically for this legume. Because they are soaked exactly the same as all non-kidney shaped beans, it is helpful for visual learners.
Lentils were the favorite of nutritional pioneer Dr. Weston A. Price due to their very high potassium content.
