An authentic Indian specialty cooked with freshly ground roasted spices, caramelised onions, and aromatic herbs in the traditional style.
Heat 1 tbsp of the oil; crackle the mustard seeds, then add the curry leaves, green chilies, turmeric, and asafoetida; pour over the mashed potatoes.
Mix well and form into 8 smooth balls, flattening each slightly.
Whisk the besan with 80ml water to a thick coating batter.
Dip each vada in the batter and deep-fry at 180°C until golden, 4-5 minutes; drain.
Toast the split buns on a hot tawa until warmed through.
Place a hot vada in each bun, press gently, and serve immediately.
