Another fun brain bender you can drop on people at your next dinner is that bananas and tomatoes are both berries but strawberries and blackberries are not.
I think it’s an important distinction because people using the term “berry” almost always are using it in a culinary context and not a botanical context.
No one wants a pie with fresh “aggregate accessory fruits”, just as much as no one would think it’s correct to call an eggplant tomato pie a dessert with “fresh berries”.
