Place the contents of two 3-ounce packages of lemon-flavored gelatin in an 8½x4½x2½-inch loaf dish. Add 2 cups boiling water and stir to dissolve gelatin. Add 1 tablespoon vinegar and 12 to 15 ice cubes; stir constantly till gelatin begins to thicken (about 3 minutes). Remove any ice cubes that have not melted.
Into the partially set gelatin snip the tops of 6 or 7 small green onions and 1 pimiento. Using scissors cut through the contents of on 1-pound can (cups) sauerkraut. Add sauerkraut to gelatin; stir gently to distribute the vegetables. Chill till set, about 4 hours or overnight. Unmold onto crisp greens on a serving plate. Garnish with ripe olives and crisp carrot curls, if desired.
Serve with Horseradish Mayonnaise: stir 1 teaspoon prepared horseradish into 1 cup mayonnaise or salad dressing; blend thoroughly. Makes 8 to 10 servings.
