A curry meal almost begs for the contrast of a cool refreshing dish. This raita serves that need nicely. Indian raitas are made of various main ingredients, bananas among them, but cucumber is by far the most frequently used.
Early in the day, grate cucumbers and stir in yogurt, ground cumin, ground coriander, black pepper, cumin seed, salt, and red pepper. Mix well; let marinate in refrigerator for several hours. Garnish with chopped fresh coriander before serving.
