4. South Indian Food - Vada
The general way of preparing vada is to make a paste or dough with gram flour or mashed or diced potatoes and/or dal lentils.

This mixture is subsequently seasoned by mixing with black mustard seeds, onion, curry leaves, which are sometimes previously sauteed, and salt, chilies and/or black pepper grains.

Often ginger and baking soda are added to the seasoning. The individual vadas are then shaped and deep-fried. Certain types of vada are covered in a gram flour batter before frying.
Although battered and deep-fried, the finished product should not be too oily if prepared correctly, since steam build-up within the vada pushes all oil away from within the vada.
Vadas are preferably eaten freshly fried, while still hot and crunchy. They are usually accompanied with coconut chutney and sambar
.

5. South Indian dish - Sambhar

Toovar dal are cooked until they are crumbled. Tamarind pulp is soaked in water to extract the flavour and then the pulp is discarded. A mixture of ground spices known as sambar powder (which contains roasted coriander seeds, chillies, lentils, and other spices) and tamarind are added to the dal. Vegetables and spices such as turmeric and chilli powder are also added. The dal and vegetable stew is heated until the vegetables cook. A wide variety of vegetables may be added to sambar. Typical vegetables include okra, carrot, radish, pumpkin, potatoes, tomatoes, brinjal and whole or halved shallots or onions, but many different vegetables may be used with adequate results. Typically sambar will contain one or several seasonal vegetables as the main vegetables in the soup.
The cooked sambar is typically eaten with an oil-fried spice mixture containing items such mustard seeds, urad dal, dried red chillies, curry leaves, fenugreek seeds, coriander seeds, and asafoetida. Fresh curry leaves or coriander leaves may be added at the very end to enhance the flavor. Curry leaves in particular are an essential element of authentic sambar; their aroma and flavor provide sambar with a distinct and pleasant herbal essence.
Sambar is reflective of a broad and ancient tradition of dal-based vegetable stews in southern India. Many regions and families of the Indian subcontinent have developed and maintained their own adaptations of a dal and vegetable stew, and similar preparations are evident in such dishes known in local languages as rasam, charu, saaru, and pappu pulusu.Most contain the common elements like toovar dal, tamarind, vegetables, sambar powder, and an oil-fried spice seed seasoning, although the soup can be made to have many different flavors depending on vegetables and selection of spices used.

Cayenne pepper, red chili powder, or other spices give it a red hue. A higher amount of Turmeric produces an orange colour. In some modern versions, both red and yellow food colourings are used. It is traditionally cooked at high temperatures in a clay oven (tandoor), but can also be prepared on a traditional grill.
