The great chefs of ancient India spent years studying the art of spice blending, both for its flavour and healing properties, and regarded their work as a form of naturopathy. "Indian spices have a power," says Malhotra. "And every one has an antidote - for example, something very spicy is always served with cooling yoghurt, and a hot curry is served with rice. Food is never made too hot, it is served with chillies, chutneys and pickles to spice it up. The balance of a meal is very important."
