Diltar refers to the yoghurt drink from Hunza Valley. Hunza people pople call it buttermilk, lassi or simply a yogurt drink. Diltar is traditionally prepared in a goat- or sheep skin which is shaken or rolled on the ground until butter forms. An alternate method uses a tall, narrow wooden cylinder and a long, thick pole in a process much like churning butter. However, nowadays, the simplest way to make Diltar is to mix yogurt with an equal amount of water and blend at high speed for a few minutes with added salt, sugar or fruits, like bananas or mangos depending on the preference of the consumer.
