Milagu Vadai or Pepper Vadai is a very popular South Indian snack. Most commonly made during Hanuman Jayanthi as an offering to Lord Anjeneya, it is also used to make delicious South Indian sambar with lots of vegetables.
The spices from the black peppercorns and the crispiness of this vadai is what makes it unique. Unlike the regular ulundu vadai, here the dal is ground to a thick batter with minimal water and then shaped into flat discs. These are then deep fried in hot oil until crisp.
