What makes these different
—
The filling is the heart of a bateta vada and the thing that most commercial versions get wrong. Ours starts with whole mustard seeds tempered in oil until they pop. The step that releases the oil in the seed and gives the filling its characteristic warmth and nuttiness. Fresh curry leaves go in next, followed by green chilli, ginger, and turmeric, and then the potato. Boiled, drained properly, and mashed with enough texture left in it to give the filling body rather than becoming a smooth paste.
Amchur, dried mango powder. This goes in at the end along with fresh coriander. This is the combination that gives the filling its brightness and stops it from feeling heavy despite the richness of the potato and the warmth of the spice.
The batter is made from besan. Chickpea flour seasoned with turmeric, red chilli, and a pinch of bicarbonate of soda that gives it a light lift and ensures the crust stays crisp rather than turning soft as the vada rests. The ratio of batter to filling matters enormously. Too thick and the batter dominates. Too thin and it doesn't protect the filling from the oil. We've found the balance just for you.
