What is the difference between a lime and a lime?

Traditional limes (also called Persian limes) and key limes have several distinct differences, including taste and texture. Key limes are smaller, rounder and more yellow-green in color than Persian limes. You’ll also find that key limes also have more seeds and a more robust, sour flavor profile compared to regular limes. Persian limes and key limes are usually used in different recipes. Key limes are commonly used in key lime pie recipes, while Persian limes are used for juice or zest in cocktails, marinades, and dressings.
