Whenever I hear the word curry, I'm filled with a longing for spicy hot food with the fragrance of cumin, cloves and cinnamon. I see deep red colours from lots of Kashmiri chillis, tinged with a suggestion of yellow from turmeric. I think of the tandoor oven, and slightly scorched naan shining with ghee and garlic.When Indians talk of their food, they talk about their life. To understand this country, you need to understand curry.
