Peanuts, Almonds, and Cashews Are Not True Nuts
Botanically, a true nut must be a hard-shelled fruit that doesn't split open to release its seed, like chestnuts or acorns. Peanuts are legumes that grow underground. Almonds and cashews are the seeds of drupes (stone fruits), like peaches or plums. Ironically, bananas and watermelons are technically berries.
