Technique Tip for Making 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 bit of oil in your pot over medium-high heat, then add the beef shank chunks and sear them on all sides until they are browned. Remove the meat and set it aside while you proceed with sautéing the onion and garlic in the same pot. This technique not only builds a deeper flavor base for your soup but also helps to lock in the juices of the beef.

How to Store or Freeze Beef Soup
Allow the Caldo de Res to cool to room temperature before storing. This helps prevent condensation, which can dilute the flavors and affect the texture of the soup.
Transfer the soup into airtight containers. For best results, use containers that are specifically designed for freezing to prevent freezer burn and maintain the quality of the beef and vegetables.
If you plan to consume the soup within a few days, store it in the refrigerator. It will stay fresh for up to 3-4 days. Make sure to label the containers with the date to keep track of freshness.
For longer storage, place the containers in the freezer. Caldo de Res can be frozen for up to 3 months. Again, label the containers with the date to ensure you use them within the optimal time frame.
When ready to reheat, thaw the soup in the refrigerator overnight if it was frozen. This gradual thawing helps maintain the texture and flavor of the beef and vegetables.
Reheat the soup on the stovetop over medium heat. Stir occasionally to ensure even heating. If the soup appears too thick after reheating, you can add a bit of beef broth or water to reach the desired consistency.
Garnish with fresh cilantro and serve with lime wedges to refresh the flavors, just as you would with a freshly made batch.
