In a large frying pan, pour in just enough water to cover the bottom. Bring to the boil and add the onion slices. Cook until the onions appear translucent. Remove the onions and finely chop them. Drain water from pan and return to the heat. Return the onions to the hot pan and brown slightly. Set aside.
Preheat oven to 180 C / Gas 4.
Soak the slice of bread quickly in the milk and squeeze it out. Set the drained milk aside. Place bread in a large mixing bowl. Mix bread together with minced beef, curry powder, 1 egg, sugar, salt, black pepper, turmeric, vinegar, chutney, almonds and raisins.
Place the mixture in a greased 28x18cm baking dish. Insert the bay leaves into the meat. Bake in a preheated oven for 1 hour.
Beat the remaining egg with 3 tablespoons of the drained milk. Pour over the meat and bake for another 30 minutes.
