The best pomegranates are ones that are juicy and sweet. When possible, buy them in season, which typically starts in September and goes through December. You can store pomegranates, which are loaded with antioxidant and anti-inflammatory properties, at room temperature for a few days or keep them in the refrigerator for up to three months.
Pick up several pomegranates, one after the other, to feel their relative weight. Select one that's heavy, which indicates it's juicy.
Rub the skin lightly with your fingers to make sure it's tight and doesn't pucker or ripple. The skin of the pomegranate should be a dark or bright red.
Make sure there are no cracks or bruises on the skin. This ensures the arils inside are still moist.
