Lassi originated in the Punjab region of the Indian subcontinent.[3] The word lassi means yogurt mixed with water in Punjabi.[5]

Lassi is prepared by blending yogurt, water, and spices. In Punjab, the yogurt is traditionally made from water buffalo milk.[4] However, variations of lassi can be prepared in different ways. Cumin and cardamom are the most common spices added to lassi.[6] Lassi is traditionally served in a clay cup known as kulhar.[6]

Namkin (salty) lassi is made by adding black pepper, cumin, and sugar to the yogurt-water mixture.[1]

Lassi masalewal (spicy lassi) is made by adding ingredients such as almonds, ginger, green chilies, and pistachios to namkin lassi.[1]

Meethi (sweet) lassi is made by adding cardamom, rosewater, and saffron to the yogurt-water mixture.[1][3]

Bhang lassi is a cannabis-infused drink that contains bhang, a liquid derivative of cannabis, which has effects similar to other eaten forms of cannabis.[7] It is legal in many parts of India and mainly sold during Holi, when pakoras containing bhang are also sometimes eaten. Uttar Pradesh is known to have licensed bhang shops, and in many places, one can buy bhang products and drink bhang lassis.[8]

Fruits such as mangos and strawberries may be added to the yogurt-water mixture to yield, for example, mango lassi and strawberry lassi.[1][3]

A 2008 print[9] and television[10][11] ad campaign for HSBC, written by Jeffree Benet of JWT Hong Kong, tells the tale of a Polish washing machine manufacturer's representative sent to India to discover why their sales are so high there.

The owner tells him he is able to "make ten times as much lassi as I used to!"
