Thandai, or sardai, is an Indian cold drink prepared with a mixture of almonds, fennel seeds, magaztari seeds (watermelon kernel), rose petals, pepper, vetiver seeds, cardamom, saffron, milk and sugar. It is native to India and is often associated with the Maha Shivaratri and Holi festival. The consumer of this Thandai is mostly from Rajasthan and Northern India.
Bhang thandai is a mildly intoxicating drink popular in many parts of the Indian subcontinent, which is made by mixing a small amount of bhang (cannabis leaves and buds) with thandai (with whole milk being used). The fat content of the milk and ground nuts help dissolve the fat-soluble cannabinoids.
