Using the blade of a sharp knife, cut about 1/4 inch deep into the skin of the pomegranate, careful not to cut through the seeds. Cut all the way around the perimeter of the pomegranate.
Twist the halves of the pomegranate apart. If they don’t separate, cut around the perimeter again – slightly deeper – until they do.
Hold one half of the pomegranate over a bowl with the seeds facing down, and firmly tap the back of pomegranate with a meat mallet or something similar. The seeds will start to fall into the bowl. Rotate the pomegranate to get as many of the seeds as possible out as you do this.
Remove the white membrane from inside the pomegranate half to loosen the remaining seeds. Also remove any membrane fragments that fall into the bowl. Repeat with the other half of the pomegranate.
