Select berries that are glossy, plump, and the deepest color of their variety, and with no sign of mushiness or mold. When berries are sold by the box, turn it upside down to make sure there is no stain or moisture on the bottom, indicating an over-ripe berry or two has dissolved. Inspect for mold - one small spot can make every berry in the box taste moldy.

When you get home, immediately spread the berries on a towel and remove any that are not perfect. Eat any crushed berries soon. Refrigerate the rest, unwashed, layered between paper towels. Just before serving, place the berries in a colander, dip into a quantity of cool water, and gently swish; then lift out, shake off the water, and gently pat dry on a cloth.
