Explanation:

 Major cereal crops in Kinnaur are barley, buckwheat and amaranth. Very little wheat and no rice is grown, and as a result, barley forms the base for each meal. It is cooked into Tsampa (baked cakes). Buckwheat is also cooked into Chilta (baked flat cake, chapati like, and slightly bitter) and Ogla (sweeter variety of Chilta).
