Here is a great make-it-from-scratch recipe
1 onion, finely diced
3 cloves garlic, crushed (or 3 tsp of crushed garlic)
1/2 tsp each of; ground ginger, cinnamon, salt, turmeric
1/4 tsp garam masala
Pinch - 1/2 tsp of chilli, depending on taste (1/2 tsp is hot)
400g cubed chicken meat
100g tomato paste (I am needing to make my own)
3/4 cup of cream
Mix the spices together and add chicken meat and set aside.
Melt butter and saute onion and garlic for 2 mins. Add chicken and saute for about 5 mins. Add tomato paste and cream and simmer gently for 5 mins.
This recipe is very flexible - you can use more cream or less cream and top up with water. You can cut down on the tomato paste or boost it to your taste.
