Using a food processor to make pork curry can help you achieve a flavorful and aromatic sauce. Start by seasoning pork shoulder with a mixture of curry powder, turmeric, cumin, and coriander. Use the food processor to finely chop onions, garlic, and ginger. Sauté the chopped vegetables in a pan until they are soft and fragrant, then transfer them to the food processor and pulse until they are finely chopped. In the same pan, sear the seasoned pork shoulder until it is browned on all sides. Transfer the pork shoulder to a slow cooker and add the chopped vegetables, along with coconut milk and broth. Cook on low for 8-10 hours, or until the pork is tender and the flavors have melded together. Serve the pork curry over rice or with naan bread for a delicious and satisfying meal.
