Ladakhi food has much in common with Tibetan food, the most prominent foods being: Thukpa, noodle soup; and Tsampa, known in Ladakhi as Ngamphe, roasted barley flour, eatable without cooking it makes useful, if dull trekking food.
A dish that is strictly Ladakhi is skyu, a heavy pasta dish with root vegetables.
As Ladakh moves toward a less sustainable, cash based economy, imported Indian foods are becoming more important. You are likely to be served rice, dal lentils with veggies even in villages without road access, and it's standard in Leh.
In leh town you can taste a vaste range of cuisines- which include north Indian, Tibetan, Chinese, Italian and even Korean. Bakeries are plenty in Leh town. Strangely they all claim to be German Bakeries. They serve seasonal fruit pies, tarts, brownies and a variety of breads.
