1) Fry the chopped onions in clarified butter or oil in a frying pan over medium heat until translucent or golden brown. Meanwhile, take the ½ onion, half of the garlic & ginger, and a pinch of salt and cook this in cooking oil over a medium heat until it is dark brown. Add this to the other fried onions.

2) Put the cooking oil in a pot and gently fry the garlic, ginger, salt, red chilli powder, garam masala powder , cumin, fenugreek, ground coriander and tomato puree. Cook for approximately 3 minutes very gently.

3) Add in the sliced tomatoes and chillies and stir well. Add in the pre-cooked lamb and stir until it is thoroughly coated. Add in the onions (that were fried). Add 1 cup of curry sauce. Simmer gently for 10-15 minutes until the lamb is heated throughly and has absorbed the flavor from the spices. Skim off any excess oil.

4) Season to taste and add in the chopped coriander/cilantro leaves and red or green chillies
