This is a traditional and very common type of raita in north India. If you dont make the boondi at home, it is an easy to make raita as well. I had this raita at my bhabhi's place with mint and it was an interesting flavor combination, so it features here as well. If you don't like mint, you can leave it out.
2 cups yogurt
1 cup savory boondi
2 tablespoons chopped mint
2 tablespoons chopped cilantro
1/2 teaspoon roasted cumin powder (bhuna jeera)
1/2 teaspoon pepper or chili powder
Whisk the yogurt till smooth and add the spices and herbs. Add water to reach the desired consistency of raita. Boondi will absorb water as it sits and become soggy, so add boondi minutes before serving. Mix well and garnish with chopped cilantro if desired.
