Vada can vary in shape and size, but are usually either doughnut- or disc-shaped and are about between 5 and 8 cm across. They are made from dal, lentil, gram flour or potato.
Vada is a traditional South Indian food known from antiquity.[2] Although they are commonly prepared at home, vadas are as well a typical street food in the Indian Subcontinent and Sri Lanka. They are usually a high calorie morning food, typically about 300 Kcal each, but in street stalls and in railway stations, as well as inside the Indian Railways, they are available as a snack all day.
