Appetizer cheesecakes are great for gatherings. You can make them ahead, they are easy to serve, and they travel well if you wish to take one to a party. Process cheese ensures a creamy smooth filling that will spread easily on crackers.
For crust, combine crushed crackers and melted margarine. Press onto bottom and about 1-1/2 inches up the sides of an 8-inch springform pan. Set aside.
Beat cream cheese with an electric mixer until softened. Add yogurt, pepper, basil, and rosemary. Beat until well blended. Add egg and egg yolk. Beat on low speed just until mixed. Stir in process Swiss cheese. Pour into crust-lined pan. Place pan on a baking sheet.
Bake in a 375 degree F. oven for 45 to 50 minutes or until nearly set in center. Cool 5 minutes on rack. With narrow spatula, loosen crust from sides of pan. Cool 30 minutes. Remove sides of pan; cool completely. When cooled, return sides of pan. Cover loosely; chill in the refrigerator for at least 4 hours or up to 24 hours. To serve, cut into small wedges; spread on crackers, bread rounds, or French bread slices. Makes 16 appetizer servings.
