Prepare to have your fruit knowledge completely turned upside down: bananas are berries, but strawberries aren't!
According to botanical definitions, a true berry must develop from a single flower with one ovary and have seeds enclosed within the flesh. Bananas check all these boxes perfectly - they develop from a single flower and their tiny black specks are actually underdeveloped seeds.
Strawberries, on the other hand, are "aggregate accessory fruits" - those little seed-like things on the outside are actually the real fruits, while the red fleshy part we eat is just enlarged stem tissue!
But the botanical surprises don't stop there. Grapes, cranberries, and even eggplants are all technically berries. Meanwhile, blackberries and raspberries aren't berries either - they're "aggregate fruits" made up of many tiny individual fruits clustered together.
Even more mind-bending: rhubarb is technically a vegetable (we eat the leaf stalks), but legally it's been classified as a fruit in the United States since 1947 for tariff purposes!
This confusion exists because botanical classifications are based on plant anatomy and reproduction, while culinary classifications are based on taste, cooking use, and cultural traditions. What we call "vegetables" like tomatoes, cucumbers, and peppers are all technically fruits from a botanical perspective.
So the next time someone corrects you about tomatoes being fruits, you can blow their mind right back by telling them about berry bananas!
