Mutton, lamb, beef and vegetable makes delightful Korma as well. If you prefer, substitute yogurt with cream or coconut milk, or a combination of them. Fried onions can be substituted with fried shallots. To prepare fried onions at home, deep-fry finely sliced onions on high heat for 10 minutes or until color changes to almost translucent and crispy. Spread out on paper towels and pat dry.
