To remove seeds from pomegranate, trim away crown of pomegranate and cut into rind in a few places. Soak fruit in cold water 5 minutes. While underwater, break pomegranate into sections and separate seeds, being careful because seeds are slippery. Remove membrane that floats to surface, and strain water to collect seeds.
