Cut the cheese into small cubes. Thinly slice some. Cut the apple into thin slices. If need be cut the gherkins into halves or quarters. Use a toothpick and skewer the grape, cheese and gherkin. It's my favorite. The perfect sweet and sour taste. For another twist try just the cheese and grape. You could also add these to the crackers. The sky is the limit on the variations of this appetizer. What other flavors will you add?
