All beans taste different so I guess I don't understand the question. A garbanzo is way different from a kidney and both way different from a butter bean.
And yet almost all of them have a basic 'bean' taste to them that I don't like. You remind me of people who tell me I just haven't had the right olive when I say I don't like olives.
I mean it's like you think I have to enjoy eating the same things you do.
Peas are part of the same family as beans. Do sweat peas taste like "beans"?
I don't think you have to like the same things I like, but I also don't think I believe it when someone writes off an entire family of plants. At least all olives are the same species. Legumes have such a huge variety that it's hard to grasp the idea of disliking them all.
