Éclat de Costilla: Short Ribs Braised in Hibiscus-Chile Coloradito with Black Truffle Purple Sweet Potato Purée

Prepare the Short Ribs: Pat the short ribs dry with paper towels. Season generously with kosher salt and black pepper. In a large Dutch oven or oven-safe pot, heat 2 tablespoons of olive oil over medium-high heat. Sear the short ribs on all sides until deeply browned, about 3-4 minutes per side. Remove ribs and set aside.

Sauté Aromatics: Add the chopped yellow onion and smashed garlic to the same pot. Sauté until softened and fragrant, about 5-7 minutes.

Deglaze and Braise: Return the short ribs to the pot. Add 4 cups of beef broth and bay leaves. Bring to a simmer, then cover tightly and transfer to a preheated oven at 160°C (325°F). Braise for 3 hours, or until the ribs are very tender and almost falling off the bone.

Prepare Chiles and Hibiscus: While ribs are braising, toast the dried ancho, guajillo, and pasilla chiles in a dry skillet over medium heat for 30 seconds per side, until fragrant. Be careful not to burn them. Transfer to a bowl, cover with hot water, and let rehydrate for 20-30 minutes. Drain and reserve a little soaking liquid. In a separate small bowl, soak the dried hibiscus flowers in 1/2 cup hot water for 15 minutes, then drain and reserve the soaking liquid.

Roast Vegetables for Mole: Preheat oven to 200°C (400°F). Place roma tomatoes, tomatillos, white onion, and garlic cloves on a baking sheet. Roast for 15-20 minutes until softened and slightly charred.

Toast Nuts and Spices: In a dry skillet, toast almonds, sesame seeds, and pumpkin seeds separately until golden and fragrant. Set aside. In the same skillet, gently toast the cinnamon stick, cloves, black peppercorns, cumin seeds, and Mexican oregano for 1-2 minutes until aromatic.

Blend the Mole Base: In a high-speed blender, combine the rehydrated chiles, soaked hibiscus, roasted tomatoes, tomatillos, white onion, garlic, toasted nuts, and toasted spices. Add 1 cup of chicken broth and blend until very smooth. If needed, add a little reserved chile soaking liquid to achieve a pourable consistency.

Cook the Mole: Heat 2 tablespoons of lard or vegetable oil in a large saucepan or pot over medium heat. Carefully pour the blended mole mixture into the hot oil (it will splatter). Stir constantly for 15-20 minutes, allowing the mole to darken and thicken. This step is crucial for developing the flavor.

Finish the Mole: Stir in the chopped dark chocolate and grated piloncillo (or brown sugar) until melted and fully incorporated. Season with salt to taste. Keep warm over very low heat, stirring occasionally. If it becomes too thick, thin with a little more chicken broth or reserved hibiscus soaking liquid.

Prepare Purple Sweet Potato Purée: Peel and dice the purple sweet potatoes. Place them in a pot and cover with cold, salted water. Bring to a boil and cook until very tender, about 15-20 minutes. Drain thoroughly.

Whip the Purée: Pass the cooked sweet potatoes through a ricer or mash very well. Return to the pot over low heat to dry out any remaining moisture. Remove from heat, then gradually whisk in the cold butter until melted and incorporated. Add the warm heavy cream and black truffle paste (or truffle). Season with kosher salt and white pepper. Whip until smooth and airy.

Assemble and Serve: Carefully remove the braised short ribs from the Dutch oven. The meat should be easily separated from the bone. Discard the bay leaves. Skim excess fat from the braising liquid, then strain the liquid and reserve.

Plating: On each plate, spoon a generous portion of the black truffle purple sweet potato purée. Place a tender short rib (or two, depending on size) on top or alongside the purée. Ladle a generous amount of the warm Hibiscus-Chile Coloradito Mole over the short ribs.

Garnish: Garnish with a sprinkle of toasted sesame seeds and fresh cilantro sprigs. Serve immediately.
