Dahi Vada Chaat is a vibrant Indian street food chaat bursting with tangy, spicy, and sweet flavors in every bite. This fun vegetarian snack is a family favorite that brings the excitement of Indian street food home.
Soak the split urad dal in water for at least 4 hours, then drain well and blend to a smooth thick paste, adding just enough water to help blend.
Whisk the dal paste vigorously until it turns light and fluffy; heat oil in a deep pan over medium-high and carefully drop spoonfuls of batter to fry vadas—fry until golden, turning occasionally for even browning.
Remove vadas and soak in warm water for 10 minutes to soften; gently squeeze out excess water without breaking the vadas.
In a bowl, whisk yogurt with sugar and a pinch of salt until smooth; arrange vadas on a platter and pour the yogurt generously over them to fully cover.
Top with boiled potatoes, chopped onions, pomegranate seeds, fresh cilantro, tamarind chutney, mint-coriander chutney, chaat masala, roasted cumin powder, chili powder, and additional salt if needed. Serve chilled or at room temperature for best flavor balance.
