Lassi (pronounced ) is a popular traditional yogurt-based drink from the Indian Subcontinent. Lassi is a blend of yogurt, water, spices and sometimes fruit. Traditional lassi (a.k.a., "salted lassi", or simply "lassi") is a savoury drink, sometimes flavoured with ground and roasted cumin. Sweet lassi, however, contains sugar or fruits, instead of spices. Salted mint lassi is highly favoured in Bangladesh.
In Indian religions, yogurt sweetened with honey is used while performing religious rituals. Less common is lassi served with milk and topped with a thin layer of clotted cream. Lassis are enjoyed chilled as a hot-weather refreshment, mostly taken with lunch. With a little turmeric powder mixed in, it is also used as a folk remedy for gastroenteritis. In Pakistan, salted lassi is often served with almost all kinds of meals, and is mostly made at home by simply whisking salt in yogurt and water. It is also sold at most dairy shops selling yogurt and milk, and both the salty and sweet variety are available.
The traditional mild sweet (or salty) form of lassi is more common in India and Punjab, Pakistan. It is prepared by blending yogurt with water with added salt. The resulting beverage is known as salted lassi. This is similar to doogh.
Sweet lassi is a form of lassi flavoured with sugar, rosewater and/or lemon, strawberry or other fruit juices.

Chaas is a salted drink similar to lassi, but may contain more water than lassi and has the butterfat removed to reduce its consistency. Salt, cumin seeds or fresh coriander may be added for taste.
