Cut the pomegranate in half vertically.
With the cut side up, make 4 equally spaced cuts, 1 inch long and 1 inch deep.
Hold the pomegranate half over a deep bowl, cut side down, and pull the fruit open but not apart, using equal pressure from both hands.
Holding the pomegranate half, cut side down, in the palm of one hand, whack the top of the fruit with the back of a large spoon. The seeds will fall out.
