Thandai is cool milk based drink made with pistachios, almonds and kesar and topped off with a large dollop of malai (cream). Bhang is often added to thicken the concoction, though it can be made without. Thandai called “baba thandai” is a special a drink to be consumed with bhang. Actually “bhang thandai” is the drink where bhang (green colored paste prepared from leaf and flower of a cannabis plant) is mixed with “thandai” heady drink alternative to alcohol. Many Tandai stores are located near the main Godowlia, and most also serve lassi. Do ask for non-bhang thandai if you want to drink plain.
