In a medium bowl, mix together the Cheddar cheese, mayonnaise, green onion, cayenne pepper, and garlic salt until well blended. Coat a ring shaped gelatin mold generously with cooking spray. Spoon the cheese mixture into the mold, cover, and chill for 2 to 3 hours to set.
Unmold onto a serving plate, and pour raspberry preserves into the center. Arrange wheat crackers around the outside of the ring.
