Technique Tip for Making This Beef Soup
When preparing beef shank for caldo de res, it's essential to sear the meat before adding it to the broth. This step locks in the flavors and adds a rich depth to the soup. Heat a bit of oil in a large pot over medium-high heat, then add the beef shank chunks, browning them on all sides. Once seared, remove the meat and set it aside. In the same pot, sauté the onion and garlic until fragrant before adding the beef broth and returning the beef shank to the pot. This technique enhances the overall taste and ensures a more flavorful caldo de res.

- For longer storage, place the containers in the freezer. The soup can be frozen for up to 3 months without significant loss of quality. Ensure the containers are freezer-safe to prevent cracking or breaking.
- When ready to enjoy, thaw the soup in the refrigerator overnight if frozen. This gradual thawing helps maintain the integrity of the vegetables and beef.
