In northern India, a dough of the main ingredient is prepared and flattened by rolling. Most Indian breads, such as roti and chapati, are baked on tava, a griddle made from cast iron, steel or aluminum. Others such as puri and bhatura are deep-fried.
In Southern India, a batter of rice and black lentils is prepared and ladled in small amounts onto a hot greased skillet, where it is spread out into a thin circle and fried with oil or ghee until golden brown. In Western India (including the states of Maharashtra,Gujarat and Rajasthan) bread may be made from coarse grains such as bajra, sorghum or ragi, though wheat is the staple in these regions. These breads are known by various names rotlo (Gujarati), bhakri (Marathi), roti (Rajasthan) or rotti (North Karnataka).
Indian breads of Central Asian origin, such as naan and tandoori roti, are baked in a tandoor. Naan is usually leavened with yeast.
The Appam is a fermented crepe usually prepared with finely powdered rice flour. In the South Indian state of Kerala , many varieties are made like Kallappam, Vattayappam and Palappam (Vellayappam). The kallappam is made on flat iron griddles. The vattayappam is a steamed bread, and palappam is made in small shallow bottomed pans, which are kept covered while the bread cooks. Palappam has a thin crisp lace like strip around it.
