This is a variation of a baked bean curry my mother used to make for the family. I think it was as a quick substitute for the normal curries she used to make and till this day remains a firm favourite for me. Ive added a few ingredients, these are the fennel seeds, tandoori masala, and the addition of onions in the first stage. You can vary the spice levels within this recipe; I think the quantities I have added would make this hot - very hot if you are not used to curries. Say perhaps a madras level. If you are reducing the spice, make sure you reduce the turmeric accordingly too. I have written 1/2 cup butter/oil/ghee but I prefer to use a combination of butter and oil. Also, I do not add salt as it is usually contained in the baked bean cans. Hope you enjoy it. I usually eat with naan, pitta bread, chappati or if im feeling naughty - a paratha.
