Raspberries and blackberries
Never wash these, or strawberries, unless they are intolerably gritty. Water is ruin to flavor and integrity, where the more delicate berries are concerned. Set on ice for an hour or more before sending to table. Pass sugar for those who wish it, and in helping out each portion avoid bruising the berries. “Mashed” berries suffer an instant change in flavor. The air begins at once to act chemically upon the liberated juices.
