Limon, also known as lime, is a citrus fruit commonly used in Mexican cuisine for its tangy and refreshing flavor. It is an essential ingredient in many dishes, including Tacos al Carbon. Limon adds a bright and zesty element to the tacos, enhancing their flavors and providing a delightful burst of acidity. The juice of the limon is often used to marinate the meat in Tacos al Carbon, adding a tangy and tenderizing effect. Limon can also be squeezed over the assembled tacos for an extra burst of freshness. Its vibrant green color and citrusy taste make it a popular choice for adding flavor and brightness to Mexican dishes.
