Indian Appetizers

Samosa (filled pastry)
A samosa is a fried or baked pastry with savory filling, such as spiced potatoes, onions, peas, lentils and sometimes with ground meat (lamb, beef or chicken), and sometimes pine nuts. Its size and consistency may vary, but typically it is distinctly triangular or tetrahedral in shape. Samosas are perhaps the most popular vegetarian Indian appetizer. They are often accompanied by a chutney such as mint, coriander or tamarind. Vegetarian samosas originated in Uttar Pradesh.
Aloo Samosa - crisp turnover filled with spiced potatoes (aloo) and peas.

Pakora/Bhaji (vegetables or paneer deep-fried in chick pea batter)
Pakoras are created by taking one or two vegetables such as onion, eggplant, potato, spinach, plantain, paneer, cauliflower, tomato, chili pepper, or occasionally bread or chicken and dipping them in a batter of gram (chickpea) flour and then deep-frying them.
The most popular varieties are pyaaz pakora, made from onion, and aloo pakora, made from potato. Other variations are paalak pakora, made from spinach, and paneer pakora, made from paneer (soft cottage cheese). When onions, on their own, are prepared in the same way, they are known as onion bhajji. A version of pakora made with wheat flour, salt, and tiny bits of potato or onion (optional) is called noon bariya (nūn=salt), typically found in eastern Uttar Pradesh in India.
In southern states of India, such preparations are known as bajji rather than pakora. Usually the name of the vegetable that is deep fried is suffixed with bajji. For instance, potato bajji is sliced potato wrapped in batter and deep fried. In such states, pakoda is taken to mean a mix of finely cut onions, green chillies and spices mixed in gram flour. This is rolled into small balls or sprinkled straight in hot oil and fried. These pakodas are very crisp on the outside and medium soft to crisp inside. There is also a variety that is softer overall, usually termed medhu pakoda in restaurants, that is made of any other ingredients, such as potatoes.
Pakoras are often served in road side eateries or restaurants. quite popular during monsoon time as pakoras goes very well with a cup of tea. the recipes for making pakoras have more or less the same indian spices and herbs and often vary in their proportions. each state of india have their own variation in making pakoras, so the recipes do differ and so does the flavor and taste.
Pakoras are usually served as snacks or appetizers and are usually complemented with tamarind chutney, cilantro chutney, or ketchup.

Seekh Kabab - finely minced lamb seasoned with fresh onions, bell peppers and spices hand-rolled into kebabs and fire roasted in a traditional clay oven.
One commenter on a recipe for Seekh Kebab says, "Great to see some Pakistani recipes! I like to brush them every few minutes with ghee (clarified butter) while on the grill. I would also highly recommend serving this with some coriander and mint raita sauce for dipping. Pulse one bunch of coriander leaves, mint leaves, some garlic cloves, one green chilli, yogurt, and some milk in a food processor until you get a thick but pourable sauce. It provides a nice cool and refreshing contrast to the hot and spicy kebabs. And don't forget the naan's!"

Vadas (fritters)
Vada is a common term for many different types of savoury fritter-type snacks from South India with a set of common ingredients. Vada is a traditional South Indian food known from ancient times. As well as being commonly prepared at home, vada are popular items in street stalls and in railway stations (including the Indian Railways). They are eaten throughout the day but most commonly as a part of breakfast alongside idlis with Sambar.
Vada can vary in shape and size, but are usually either doughnut- or disc-shaped and are between 5 and 8 cm across. Vada are generally prepared from a thick batter of Black gram or coarsely ground Bengal gram which has been fermented. This mixture is then seasoned by mixing with cumin seeds, onion, curry leaves (sometimes previously sauteed), salt, chillies and/or black pepper grains. Often ginger and baking soda are added to the seasoning in shops to increase the fluffy texture and improve fermentation for large batches. Homemade Vada generally do not incorporate baking soda and rely on natural fermentation (relatively easy in South India). The individual vada are then shaped and deep-fried. Although battered and deep-fried, the finished product should not absorb the oil since steam build-up within the vada keeps the oil out. The final result is a crispy deep-fried skin around a light and fluffy centre.
The standard accompaniment to vada is a helping of coconut chutney and a watery Sambar.
