When peanuts are roasted or fried, as they commonly are, they become that crunchy and “nutty” little treat that most of us are familiar with, but, technically, peanuts are not (tree)nuts. Peanuts are a type of legume: edible seeds that grow in pods, like beans and peas. And like beans and peas, when peanuts are boiled in (salted) water, they soften and become super tasty. These boiled, salty, soft peanuts are totally addictive and make for a delicious snack.
