How to Make It
Preheat oven to 400°.
Combine 1/3 cup sugar, crumbs, and butter. Press mixture into bottom and 1/2 inch up sides of a 9-inch springform pan coated with cooking spray. Bake at 400° for 7 minutes. Cool on a wire rack.
Reduce oven temperature to 325°.
Combine 1/3 cup sugar, 1/2 cup water, juice, and guava paste in a small saucepan; bring to a boil. Reduce heat, and simmer 5 minutes, stirring occasionally. Cool slightly. Pour mixture into a blender, and process until smooth. Cool completely. Stir in 1 egg white.
Combine remaining 1 cup sugar, sour cream, and cheese in a medium bowl; beat with a mixer at low speed until smooth. Beat in vanilla and salt. Gradually add remaining 4 egg whites, beating well after each addition. Pour cheese mixture into prepared pan. Drizzle guava mixture over cheese mixture; swirl mixtures using the tip of a knife. Bake at 325° for 45 minutes or until cheesecake center barely moves when touched.
Turn oven off; cool cheesecake in closed oven 30 minutes. Remove cheesecake from oven. Run a knife around outside edge. Cool to room temperature. Cover and chill at least 8 hours before serving.
