## What is Sopa de Cola?
*Sopa de Cola* literally translates to “oxtail soup.” It’s a traditional Mexican soup featuring oxtail as the star ingredient. The oxtail is slow-cooked until incredibly tender, releasing its rich collagen and creating a deeply flavorful broth. The soup is typically infused with a variety of chilies, herbs, and spices, giving it a warm and comforting heat. Common additions include vegetables like carrots, potatoes, celery, and tomatoes, adding texture and nutritional value. Some variations also incorporate rice or noodles for a heartier meal.
The beauty of *Sopa de Cola* lies in its ability to transform a humble cut of meat into a culinary masterpiece. The slow cooking process allows the oxtail to impart its unique flavor and richness to the broth, creating a truly unforgettable soup.
## Why Oxtail?
Oxtail, despite being a less commonly used cut of meat, is prized for its exceptional flavor and texture. It’s rich in collagen, which breaks down during cooking, resulting in a silky, gelatinous broth. This collagen also contributes to the soup’s incredible body and mouthfeel. Furthermore, oxtail is incredibly flavorful, with a deep, beefy taste that is enhanced by the slow cooking process.
Don’t be intimidated by the appearance of oxtail. While it may seem bony, it’s surrounded by plenty of meat and connective tissue that renders beautifully during cooking, creating a tender and flavorful result.
## Key Ingredients for Authentic Sopa de Cola
Here’s a breakdown of the essential ingredients you’ll need to create a truly authentic *Sopa de Cola*:
* **Oxtail:** The star of the show! Look for meaty oxtail pieces. About 2-3 pounds should suffice for a large pot of soup.
* **Dried Chilies:** This is where the heat and flavor come from. Common choices include:
* **Ancho Chilies:** Mildly spicy with a fruity, raisin-like flavor. A staple in many Mexican dishes.
* **Guajillo Chilies:** Moderately spicy with a slightly sweet and smoky flavor.
* **Pasilla Chilies:** Mild to medium heat with a rich, earthy flavor.
* You can use a combination of these chilies to create a complex flavor profile.
* **Aromatics:** These form the foundation of the soup’s flavor:
* **Onion:** Yellow or white onion works best.
* **Garlic:** Plenty of garlic cloves are essential.
* **Tomatoes:** Roma tomatoes or canned crushed tomatoes.
* **Herbs and Spices:** These add depth and complexity:
* **Bay Leaves:** Provide a subtle herbal aroma.

* 1 tablespoon Mexican oregano
* 1 teaspoon ground cumin
* 1/2 teaspoon coriander seeds, lightly crushed (optional)
* 2 whole cloves (optional)
* 2 carrots, peeled and chopped
* 2 potatoes, peeled and cubed
* 2 celery stalks, chopped
* 1 cup corn kernels (fresh or frozen)
* Salt and black pepper to taste
* Fresh lime wedges, for serving
* Fresh cilantro, chopped, for garnish
**Instructions:**
**1. Prepare the Chilies:**
* Remove the stems and seeds from the dried chilies.
* Toast the chilies in a dry skillet over medium heat for a few seconds per side, until fragrant. Be careful not to burn them.
* Place the toasted chilies in a bowl and cover them with hot water. Let them soak for at least 30 minutes, or until softened.
**2. Sear the Oxtail:**
* Season the oxtail pieces generously with salt and black pepper.
* Heat the olive oil in a large Dutch oven or heavy-bottomed pot over medium-high heat.
* Sear the oxtail in batches, browning on all sides. This step is crucial for developing flavor. Don’t overcrowd the pot; work in batches to ensure proper browning.
* Remove the oxtail from the pot and set aside.
**3. Sauté the Aromatics:**
* Add the chopped onion to the pot and sauté until softened and translucent, about 5-7 minutes.
* Add the minced garlic and cook for another minute, until fragrant.
* Add the chopped tomatoes (or crushed tomatoes) and cook for a few minutes, stirring occasionally, until they begin to break down.
**4. Blend the Chili Sauce:**
* Drain the soaked chilies, reserving the soaking liquid.
* Place the softened chilies in a blender along with about 1 cup of the reserved soaking liquid.
* Blend until smooth, adding more soaking liquid if needed to achieve a smooth consistency.
* Strain the chili sauce through a fine-mesh sieve to remove any seeds or skins. This will ensure a smoother soup.
**5. Combine and Simmer:**
* Pour the strained chili sauce into the pot with the sautéed aromatics.
* Add the beef broth, bay leaves, Mexican oregano, cumin, coriander seeds (if using), and cloves (if using).
* Return the seared oxtail to the pot.
* Bring the soup to a boil, then reduce the heat to low, cover, and simmer for at least 3-4 hours, or until the oxtail is very tender and falling off the bone. Check the liquid level periodically and add more broth or water if needed.
**6. Add the Vegetables:**
* After the oxtail has simmered for about 2 hours, add the carrots, potatoes, and celery to the pot.
* Continue to simmer for another hour, or until the vegetables are tender.
* Add the corn kernels during the last 15 minutes of cooking.
**7. Season and Serve:**
* Remove the bay leaves and cloves (if using) from the soup.
* Taste the soup and adjust the seasoning with salt and black pepper as needed. The broth should be rich and flavorful. If it needs more depth, consider adding a small amount of bouillon or a teaspoon of tomato paste.
* Serve hot, garnished with fresh cilantro and a squeeze of fresh lime juice.
## Tips for the Best Sopa de Cola
* **Don’t skip the searing:** Searing the oxtail is crucial for developing a rich, deep flavor in the soup. It creates a Maillard reaction, which adds complexity and depth to the final dish.
* **Toast the chilies:** Toasting the dried chilies before soaking them enhances their flavor and aroma. Be careful not to burn them, as this will make them bitter.
* **Strain the chili sauce:** Straining the chili sauce ensures a smooth and velvety soup. It removes any seeds or skins that can make the soup gritty.
* **Simmer low and slow:** The key to tender oxtail and a flavorful broth is slow cooking. Simmer the soup over low heat for several hours, allowing the flavors to meld together.
* **Skim off any impurities:** During the simmering process, you may notice some foam or scum rising to the surface of the soup. Skim this off with a spoon to ensure a clear and flavorful broth.
* **Adjust the spice level:** The amount of chilies used in this recipe can be adjusted to your preferred spice level. If you prefer a milder soup, use fewer chilies or remove the seeds and membranes from the chilies before soaking them.
* **Bone Broth Boost:** To further enhance the nutritional value and flavor of your soup, consider using homemade bone broth instead of store-bought broth. Bone broth is rich in collagen and minerals, adding depth and richness to the soup.
* **Degreasing:** Oxtail can release a significant amount of fat during cooking. After the soup has cooled slightly, you can skim off the excess fat from the surface. Alternatively, you can refrigerate the soup overnight and remove the solidified fat the next day.
* **Make it Ahead:** Sopa de Cola is even better the next day, as the flavors have more time to meld together. You can make the soup a day or two in advance and store it in the refrigerator. Reheat thoroughly before serving.
## Variations and Additions
* **Add Rice or Noodles:** For a heartier meal, add cooked rice or noodles to the soup during the last 15-20 minutes of cooking. Rice is a very traditional option. Small pasta shapes like ditalini or elbow macaroni also work well.
* **Add Other Vegetables:** Feel free to add other vegetables to the soup, such as green beans, zucchini, or chayote squash.
* **Spicy Kick:** For extra heat, add a chopped serrano pepper or a pinch of cayenne pepper to the soup.
* **Smoked Oxtail:** Using smoked oxtail adds a fantastic layer of smoky flavor to the soup. You may need to adjust the cooking time depending on how tender the smoked oxtail is.
* **Instant Pot Version:** While the traditional method involves slow simmering, you can also make Sopa de Cola in an Instant Pot. Sear the oxtail as directed, then add all the ingredients to the Instant Pot. Cook on high pressure for 45-50 minutes, followed by a natural pressure release.
* **Slow Cooker Version:** You can also adapt this recipe for a slow cooker. Sear the oxtail as directed, then add all the ingredients to the slow cooker. Cook on low for 8-10 hours, or on high for 4-5 hours, or until the oxtail is very tender.
## Serving Suggestions
* **Garnishes:** Serve *Sopa de Cola* hot, garnished with fresh cilantro and a squeeze of fresh lime juice. Other optional garnishes include chopped onion, diced avocado, and a dollop of sour cream or Mexican crema.
* **Sides:** Serve with warm tortillas or crusty bread for dipping into the flavorful broth.
* **Make it a Meal:** A simple side salad can round out the meal.
