Peel and finely chop cucumber, then remove watery seeds if needed.
Build the yogurt base
Whisk chilled yogurt in a bowl until smooth and creamy.
Add roasted cumin powder, black salt, and regular salt.
Finish the raita
Fold in mango and cucumber gently so the cubes stay intact.
Taste and add sugar only if the mango needs more sweetness.
Chill for ten to fifteen minutes, garnish with herbs, and serve cold.
Notes
For thicker texture, use hung curd or Greek yogurt.To prevent watery raita, add cucumber close to serving time.For vegan raita, use unsweetened coconut or almond yogurt and add a squeeze of lemon.Store in an airtight container in the refrigerator for up to one day.
