Lassi
What it is
Lassi is a yogurt-based drink, blended from dahi with water and a flavoring, served chilled and ranging from a thin, savory cooler to a thick, almost spoonable sweet treat. It is the iconic drink of the Punjab and a defining everyday refreshment of North India.
How it's made
Dahi is whisked or blended with water (and sometimes a little milk or cream) until smooth and frothy, then sweetened or salted and flavored. Sweet lassi takes sugar and often rosewater or cardamom; salty (namkeen) lassi takes salt, roasted cumin, and sometimes mint; mango lassi blends in ripe mango or mango pulp. Punjabi lassi is made especially thick and topped with a layer of malai.
Flavor profile
Tangy yogurt brightened by its flavoring: sweet and floral, savory and cumin-scented, or fruity and lush in the mango version. Texture ranges from pourable to thick and creamy, always cooling.
Culinary uses
Lassi is a drink, not a cooking ingredient — served as a refreshment and a foil to spicy food, taken with or after a meal. The thick sweet Punjabi version verges on dessert; the salty version functions as a digestive and cooler in hot weather.
Regional variations
Punjabi sweet lassi (thick, malai-topped, served in tall metal glasses) is the most famous. Mango lassi is a near-universal restaurant offering. Salty/spiced versions dominate in hotter, drier regions as a working-day cooler. A close relative, chaas, is thinner and savory (see below).
Cultural & historical context
Lassi is bound up with Punjabi village and farming culture, where a thick glass topped with cream was a substantial midday refreshment. Why substitution fails: blending Western yogurt with water yields a thin, bland drink; the body and tang of dahi (especially buffalo-milk dahi) are what give lassi its character, and a thick Punjabi lassi in particular depends on yogurt rich enough to stay creamy when diluted.
