Prepare Cucumber Raita: With vegetable peeler, remove several strips of peel from each cucumber. Cut each cucumber lengthwise in half; scoop out seeds. Cut each half lengthwise in half, then crosswise into 1/2-inch-thick pieces. In medium bowl, toss cucumbers with 1/4 teaspoon salt; let stand 10 minutes. With hand, press cucumbers to remove as much liquid as possible; drain off liquid. Stir in yogurt, mint, sugar, and remaining 3/4 teaspoon salt. Cover and refrigerate until ready to serve or up to 6 hours. Makes about 4 cups.
