Chai, I have been hearing of people who soak beans before cooking, hearing this from a westerners surprised me and afirm the claim.
When I want to cook beans, I boiled it on low heat for like 5-10minutes, put off the gas and let it rest for like 30 minutes before resuming back to cooking.
With that, the beans get done faster and flatulence is removed.
Interesting technique! I think you would find that soaking the beans, throwing out that water, then boiling in new water will make them even more digestible.
Thanks for your input!
