The basic method of making this curry remains exactly same as the 15 minutes Thai Curry. However this curry takes much longer than 15 minutes. Only because of cooking time for goat. As per my experience goat tastes the best when cooked in slow cooker. You may use pressure cooker also. All that you need to do is cook goat with 3-4 cups of water, 1 tsp salt and 1/2 tsp turmeric for 4/6/8/10 hours based on how much time you have. If using pressure cooker then cook for 4-5 whistles. When cooked separate the cooked goat and stock. Use cooked goat exactly the way you would use chicken in 15 minutes Thai Curry. Ofcourse patience pays, so this curry is way tastier than chicken or shrimp curry.
