Elements common to all culinary specialties are curry and spices. All dishes have very strong, concrete flavors but with a tone and a flavor that cannot be found in other types of international and world cuisine.The Indian dishes and preparations are truly endless and differ in the various styles in which they are cooked. First of all, there are stewed preparations or cooked in casseroles, which can be based on chicken, lamb, fish or shellfish; the second technique with which Indian specialties are prepared is the Tandoori oven, a large vessel made of clay and lava stone in which food is cooked, and at the level of gustatory perceptions it is very reminiscent of cooking on the grill.
