Making sure that te vadas are cooked evenly

No undercooked dough, no burnt lines, or soggy middle, all you get is just crispy deliciousness.

A better texture

This unique, doughnut-like design helps create that ideal contrast: Crispy exterior and a soft, airy centre, giving you that satisfying bite every time.

A time-tested technique

In most Indian households, or the street vendors, shape the vadas by hand, styled as a ring, and then gently slid into hot oil. This method has been passed down for generations, and the hole isn't just practical, it's part of the vada's identity.

Ease of frying

A solid dough ball akes a lot of time to cook, and cooking it evenly is a task too. The hole allows heat and oil to penetrate uniformly, making it easier for home cooks to get it just right.
