Cut the pomegranate in half horizontally.

Put one half in your hand, cut side down. Place your hand over a large mixing bowl.

Using a wooden spoon, smack firmly on the top of the pomegranate repeatedly. Keep your fingers loose so that the pomegranate seeds can fall into the bowl.

Keep smacking until all the seeds are removed. 

Do the same for the other half.

Remove the white membrane bits from the bowl. Just pick them with your hand and discard. Alternatively, you can pour water into the bowl and you will see those bits will float. Discard them with a slotted spoon.

Eat immediately or store it in the fridge in an airtight container for about a week. 

To freeze: Line a baking sheet or a large plate with parchment paper. Put the pomegranate seeds in a single layer. Keep them in the freezer for 2 hours. When they are frozen, transfer them into a resealable freezer bag. They keep well for 3-4 months.
