“Dry" berries are good berries! To make sure you pick the best blueberries, be sure they are dry and dark purple. Red berries aren’t ripe – once a blueberry is picked, it doesn’t ripen anymore. Try dehydrating the berries in an oven at a low temperature. This will intensify the flavor. Dehydrated blueberries are chewy, a little bit sweeter and will last longer.
