Crust: Preheat oven to 325°F (163°C). Mix graham cracker crumbs, sugar, and melted butter. Press into an 8-inch springform pan (2¾ inches deep). Bake 10 minutes; cool.
Raspberry Swirl: Cook raspberries, sugar, and lemon juice over medium heat for 5-7 minutes. Strain to remove seeds; cool.
Filling: Beat cream cheese until smooth. Add sugar, lemon zest, lemon emulsion, and vanilla. Add eggs one at a time, then fold in sour cream.
Assemble: Pour filling over crust. Drop spoonfuls of raspberry puree on top; swirl with a toothpick.
Bake: Wrap pan tightly in foil. Place in a roasting pan with hot water halfway up the sides. Bake 65-80 minutes until edges are set and center jiggles (150°F). Cool in oven, door cracked, for 1 hour.
Chill: Refrigerate 4+ hours. Garnish with whipped cream, raspberries, and zest. Serve!
Notes
Pan Size: Use a 9-inch pan for a thinner cheesecake; no adjustments needed.
Storage: Refrigerate 5 days or freeze 2 months.
Foil Tip: Don’t skip the foil wrap to avoid a mushy crust (trust me!).
