In a small heavy saucepan combine the 2/3 cup sugar with the water, bring the mixture to a boil, gently swirling the pan and washing down any sugar crystals clinging to the sides of the pan with the brush dipped in cold water, and boil the syrup until it reaches the soft-ball stage, or the candy thermometer reaches 238 degrees F. In the bowl of the upright mixer beat the egg whites with the salt until they hold stiff peaks.

With the mixer running, add the sugar syrup in a stream and beat the egg whites until cool.
