De-seeding pomegranates is easy, although it can be a bit messy as they tend to stain. First, roll a pomegranate on the counter a few times. This helps to loosen the seeds inside. Then cut it in half. Hold one half over a large bowl with the seeds facing down. With the other hand, use the back of a wooden spoon and whack it hard a few times to knock out all the seeds. Then remove the pith (the white membrane) that may fall into the bowl. To make the juice, I cut the pomegranate in half and squeeze it just like when I make orange juice.
