Ingredients:
- 3 lbs beef shanks (Chamorro), cut into 2-inch thick rounds
- 1 lb beef marrow bones (Tuétano)
- 4 quarts cold filtered water
- 2 tbsp sea salt
- 1 large white onion, halved
- 1 head of garlic, sliced crosswise
- 2 dried bay leaves
- 1 tsp black peppercorns, whole
- 3 ears of corn (Elote), husked and cut into thirds
- 2 large carrots, peeled and cut into thick chunks
- 2 chayotes, cored and sliced into wedges
- 3 medium Yukon Gold potatoes, halved
- 0.5 small head of green cabbage, cut into thick wedges
- 1 bunch fresh cilantro, tied with kitchen twine
- 4 limes, quartered
- 2 serrano peppers, finely minced
- 1 cup radishes, thinly sliced
Instructions:
- Place the beef shanks and marrow bones in a 12-quart stockpot and cover with 4 quarts of cold filtered water.
- Bring to a gentle simmer over medium heat. As soon as gray foam rises, use a skimmer to remove it. Do this for about 15 minutes.
- Add the halved white onion, garlic head, bay leaves, peppercorns, and sea salt.
- Reduce heat to the lowest setting. Cover partially and cook for 2 hours until the beef begins to pull away from the bone.
- Add the corn to the pot.
- Add the carrots and potatoes to the pot. Simmer for 20 minutes.
- Add the chayote and cabbage wedges. Continue to simmer until the potatoes are fork-tender and the cabbage is translucent, approximately 20-30 minutes more.
- In the final 5 minutes, add the tied bunch of cilantro to infuse the broth. Remove the cilantro bundle before serving.
- Serve the soup in large bowls ensuring each portion gets meat, bone marrow, and a variety of vegetables. Garnish with lime juice, minced serrano peppers, and sliced radishes. Serve with warm corn tortillas.
