Key Limes are smaller than those regular Persian Limes, only about one inch in diameter. They have very thin rinds, are more acidic, and are almost yellow when ripe. They have a stronger flavor, too, that’s more like both lemon and lime at the same time. And, for the record, they also come from many parts of the Middle Americas and the Caribbean. In fact, they are called Mexican Limes in most other places. https://casualmondaycharters.com/the-best-key-lime-pie-in-key-west/
