Take the beef in a large bowl. Add the onion, green chillies, ½ teaspoon of turmeric powder, ½ teaspoon of chilli powder 1 teaspoon of meat masala, garam masala powder, ginger garlic paste, one one leaflet of curry leaves and salt. Mix thoroughly and let it marinate for at least half-an-hour. Pressure cook the beef with ½ cup of water.
In a pan, sauté the grated coconut, shallots along with one leaflet of curry leaves. Once the coconut turns golden brown, add ¼ teaspoon of turmeric powder, 1 teaspoon of meat masala, ½ teaspoon of coriander powder, ½ teaspoon of chilli powder and mix well.
