Technique Tip for This Beef Soup
When preparing beef shank for caldo de res, it's essential to sear the meat before adding it to the pot. This step enhances the flavor by creating a rich, caramelized crust on the beef. To do this, heat a small amount of oil in a large pot over medium-high heat, then add the beef shank chunks and cook until they are browned on all sides. Remove the beef and set it aside while you sauté the onion and garlic in the same pot. This technique not only adds depth to the broth but also ensures that the beef remains juicy and flavorful throughout the cooking process.
