Fill a bowl with the berries, leaving enough room for ice. Then, place ice cubes on top of the berries and pour water into the bowl so the ice begins to float.
This trick works because the porous strawberries soak up the ice water, becoming plump. However, if they’re too ripe, submerging them in water for too long can make them mushier.
If the ice water trick doesn’t work, you can always cut off the affected parts, freeze the strawberries for smoothies, or make them into a sauce, syrup, jam, or purée.
