For a richer flavor, use full-fat Greek yogurt. If you prefer a tangier taste, omit the sugar or add a squeeze of fresh lemon juice. To easily remove pomegranate seeds, cut the pomegranate in half and submerge it in a bowl of water. Gently loosen the seeds with your fingers; they will sink to the bottom while the membrane floats to the top. Strain and discard the membrane. Raita can be made ahead of time and stored in the refrigerator for up to 24 hours. However, the pomegranate seeds may release some of their color, slightly tinting the yogurt. Serve this raita as a refreshing accompaniment to grilled meats, spicy curries, or vegetable dishes. It also makes a delicious and healthy snack on its own.
