Butter chicken is chicken in a tomato-based sauce with spices. It is served in Indian food restaurants. I get a pre-made spice kit from the local Indian market. This is what I did:
Mix together 1/2 c. water, spices and 4 table spoons lemon juice.
Marinate 1 lb of chicken breasts (cut into cubes) in the mixture of an hour.
Boil 2 lbs of tomatoes until soft and then separate the skins and seeds.
Cook chicken in the marinade and tomato puree for 20 minutes.
When it is cooked through turn off the heat and add a 1/2 cup milk and a stick of butter.
It is so yummy!
