Caldo de Res is a traditional Mexican beef soup that features a rich and flavorful broth. It typically includes large chunks of beef, often with bone, which adds depth to the flavor. The soup is simmered for several hours, allowing the meat to become tender and the flavors to meld together. In addition to beef, Caldo de Res is usually packed with a variety of vegetables such as carrots, potatoes, corn, and zucchini. It is often served with fresh herbs like cilantro and accompanied by lime wedges and tortillas for a complete meal.
