Now, step into the kitchen. Chefs and home cooks don’t care about botany at all. They care about flavor and how you use the thing. If it’s sweet and goes in dessert, it’s a fruit. If it’s savory and goes in a salad or stir-fry, it’s a vegetable.
That’s why a tomato—a botanical fruit—ends up in pasta sauce and on pizza. We call it a vegetable because it tastes like one. Same goes for bell peppers, eggplant, and avocado (yes, avocado is a fruit too—and a sexy one at that).
Where It Gets Really Silly
Remember the Supreme Court case from 1893? No? Well, the U.S. government had to decide if tomatoes were fruits or vegetables for tax purposes. They ruled that tomatoes are vegetables because people eat them with dinner, not for dessert. So, legally, a tomato is a vegetable. Take that, botany!
And what about pumpkins? They’re fruits (seeds inside, grew from a flower), but we call them “winter squash”—which sounds like a vegetable. And then we carve them into jack-o’-lanterns, which is not a food group at all.
