The flower end of the pomegranate has a small blossom growing out of it is.
There should be 4-6 ridges on your fruit. The pomegranate will naturally separate along these ridges, making it easier to cut and open the fruit.
Pull the sections apart gently to avoid spilling any seeds. If a few do get loose, gather them up on your surface so you can clean them.
If any seeds fell out of your pomegranate while you were opening it, place those in the water as well.
Besides making it easier to open the fruit, the warm water will also wash the seeds.
Whack the section 3-4 times, or until most of the seeds have fallen out.
If the pieces are large enough, you can also pick them out with your hands.
You can also store the seeds in an airtight container. Place them in the refrigerator for 5 days, or freeze them for up to 3 months.
