COOK'S NOTES: This is a mild curry, perfect for those starting out in the world of curries. Sandwiched between the Middle East and the Indian subcontinent, Afghanistan's food has been influenced by the cuisines of all the countries in these areas. In this recipe, its Iranian and Turkish influences are shown by the addition of nutmeg and cinnamon, while the rich, thick sauce from the combined tomato, stock and spinach resemble a traditional Indian curry. The tender green leaves of spinach are often added to soups, stir-fries and curries just before serving.
