SPICY LAMB BOLOGNESE

Steps:

• Heat a medium Dutch oven over medium heat. Add the butter and oil and warm until the butter is melted. Add the carrots, celery, onions and 1/2 teaspoon salt. Cook, stirring often, until the vegetables are soft but have no color, about 6 minutes. Add the beef and lamb and cook, breaking apart the meat with a wooden spoon, until the meat is cooked through and no longer pink, about 5 minutes. Stir the tomato paste, chili paste, red pepper flakes and garlic into the meat mixture. Cook the tomato paste, stirring often, about 2 minutes. Add the milk. Bring to a simmer and cook, stirring occasionally, until the milk is almost entirely evaporated, about 20 minutes.
• Add the wine, bay leaf, Parmesan rind, tomatoes and 1/2 teaspoon salt. Bring to a simmer and reduce the heat to low to just maintain a gentle simmer. Simmer the sauce, stirring occasionally to prevent sticking, 1 1/2 to 2 hours. Skim the oil from the surface.
• Spoon the sauce over the Creamy Polenta with Spinach, reserving any extra to serve on the side. Serve with the Parmesan sprinkled over the top and a drizzle of olive oil.
• In a Dutch oven, bring the chicken broth, oil, garlic and 1 1/2 cups water to a boil over medium-high heat. Reduce the heat to medium low and whisk in the polenta. Season with 1/2 teaspoon salt and cook, stirring occasionally with a wooden spoon, about 10 minutes. Stir in the Parmesan, mascarpone, pecorino and butter. Cook, stirring often, about 5 minutes. Fold in the spinach and cook until wilted, about 5 minutes longer. Add 1/4 cup water if the mixture gets too thick.
• Pour the polenta onto a large board or platter. Serve with grated Parmesan over the top.
