Making Curry

Today I made some Yellow Chicken Curry. The recipe I used was, 3 tablespoons of olive oil, 1 small onion chopped, 2 cloves of garlic, 3 tablespoons of curry powder, 1 teaspoon of ground cinnamon, 1 teaspoon of paprika, 1 bay leaf, a half of a teaspoon of fresh ginger root, half of a teaspoon of white sugar, 2 skinless, boneless chicken breasts cut into bite size pieces, 1 tablespoon of tomato paste, 1 cup of plain yogurt, 3 fourths of a cup coconut milk, half of a lemon juiced, and half of a teaspoon of cayenne pepper. When it cooked and was finished I tried the curry and it was hot( Tempature wise), spicy, and bland. It didn't have any taste in the middle.
