How to cook beans

When I moved back to Houston last year, I continued my practice of cooking new things. I decided to try cooking beans instead of buying them from the can. I'd heard different ways to cook beans, but I wasn't sure which was right. I went to the Internet and found an article by Katherine Sacks on Epicurious entitled Epicurious's Myth-Busting Guide to Cooking Beans. I used that for cooking pintos twice last year. Hopefully the article will serve me well again.

I initially posted that I'd gotten interested in lima beans after learning that they have the most protein of all the vegetables. Then I learned that wasn't true! I was comparing the nutrition information on the lima beans with a package of pinto beans I had. Pinto beans have more protein. Then I looked at a package of lentils. They have even more protein than pinto beans. I then found a page showing the top ten beans ranked by protein, and it puts lima beans at the end of the list. Number one is soybeans. Interestingly enough, that page on the same website as the erroneous page.
