Select berries that are in dry unstained containers. Stained containers may indicate oversoft berries that are not freshly picked. Mold on berries spreads quickly. Never leave a moldy berry next to a good one.
The best time for this dessert is mid-summer, when the blueberries are thick in our northern woods. Red raspberries can be added to the mixed berries, too, to brighten up the patriotic colors.—Anne Theriault, Wellesley, Massachusetts
