Ingredients Method Notes

Ingredients
  

Crust Ingredients
  • 1 cup graham cracker crumbs Classic base; can switch to vanilla wafers for a lighter sweetness.
  • 1/2 cup unsalted butter Melted, to bind the crust.
  • 1/4 cup granulated sugar Used in both crust and filling to balance acidity.
Filling Ingredients
  • 16 oz cream cheese Full-fat, softened and at room temperature.
  • 1/2 cup sour cream or Greek yogurt Adds tang and a soft custardy finish.
  • 3 large eggs Room temperature; add one at a time and mix gently.
  • 1/2 cup fresh Key lime juice The star ingredient; fresh is essential.
  • 1 tbsp Key lime zest Zest first, then juice; use a light hand.
  • 1 tsp vanilla extract Adds warmth to the flavor.
  • 2 tbsp cornstarch Helps stabilize the delicate texture.
  • 1 pinch salt Sharpen flavor.

Method
 

Preparation
  1. Preheat your oven to 300°F (150°C).
  2. In a bowl, mix graham cracker crumbs, melted butter, and sugar until combined. Press into the bottom of a springform pan and prebake for 8 to 10 minutes.
  3. In a separate mixing bowl, beat the cream cheese until smooth. Gradually add the sugar and combine.
  4. Add sour cream, lime zest, lime juice, vanilla, cornstarch, and salt. Mix until fully incorporated.
  5. Add eggs one at a time on low speed, mixing gently after each addition.
Baking
  1. Pour the filling over the pre-baked crust.
  2. Set the springform pan into a larger pan filled with hot water or place a pan of hot water on the rack below to create humidity.
  3. Bake for about 60 minutes, or until the edges are set and the center wobbles slightly.
Cooling
  1. Run a thin knife around the edge of the cheesecake 10 minutes after removing it from the oven.
  2. Allow it to cool gradually, and chill in the refrigerator for at least 6 hours or overnight before slicing.

Notes

For a crack-free top, control temperature and moisture. Avoid high heat. Key limes give the best flavor, but regular limes can be used in a pinch by mixing with lemon juice.
