A popular chilled yogurt drink in India, which can also be made with buttermilk or extra-rich milk. Lassi is like a healthy milk shake, the thickness of which depends on the ratio of yogurt to water. Thick lassi is made with four parts yogurt to one part water and/or crushed ice. Lassi can be flavored variously with salt, mint, cumin, sugar, fruit or fruit juices — even spicy additions such as ground chiles, fresh ginger or garlic. The ingredients are all placed in a blender and processed until the mixture is light and frothy.
