Using the hand whisker, whisk the curd well, so there are no lumps and curd is smooth.
First we will add the spices-black pepper powder, roasted cumin seed powder, black salt, and 1/4th tsp salt.
Now chopped green chilies, mint leaves, coriander, onions, cucumber and tomatoes. And mix well.
I would advise you to avoid using water because onion, tomato, and cucumber are high in water content.
Refrigerate for a while and then transfer the raita into a serving bowl.
