But what are butter beans? When my brother in Canada said he'd never heard of them, his first question was whether they were the same as lima beans. I firmly told him no way. Lima beans are green and have an asringent alum-like taste. Butter beans are a pale whitish-yellow and, as their name suggests, have a creamy taste. I never liked limas but I find butter beans very palatable.

Yet a quick search online suggests that the beans are related, if not the same thing. There are at least three competing theories: lima and butter beans are exactly the same; they are the same thing at different stages of development; they are different. Confusion reigns. My taste bud tells me the third option is the correct one.
