Sev (noodles) are shaped with Seviya machine, a unique brass utensil equipped with different interchangeable disks. A fine-holed disk is attached to the container and filled with dough, which is then pressed into hot oil where it fries into crisp noodles. The utensil has two disks - thin & thick. It is available at most of the Indian grocery stores.

Ingredients: (Serves : 6) 

21/2 cups sifted chickpea flour (Besan)
1tbsp. vegetable oil
11/2tbsp. salt
1/2tsp cayenne powder
1/2tsp. turmeric powder
1/2tbsp. lemon juice
3/4th cup water
Ghee / oil for deep frying

Preparation:

Mix the flour, salt, cayenne & turmeric powder in a bowl. Add 1tbsp oil & lemon juice to the water. Pour it in the flour and mix into a thick paste, adding extra flour as necessary so that the mixture is not sticky. It should be mashed potatoes texture.
Fill the seviya machine with a portion of it.
Heat the oil / ghee in a kadhai / deep-frying pan over moderate heat.
Holding the utensil over the hot oil, force the mixture through the holes by turning the handle.
As soon as noodles fall, slowly move the machine in a circular motion so that they do not stick together.
Fry both sides until crisp and lightly browned.
Remove and drain on a paper towel. Fry the remaining paste in the same manner.
Cool and break into uniform pieces.
Keep in an air tight container for 2 weeks.
