Ingredients:
- 1.5 cups (150g) Graham cracker crumbs
- 0.33 cup (65g) Granulated sugar
- 6 tbsp (85g) Unsalted butter, melted
- 0.5 tsp Sea salt
- 14 oz (397g) Sweetened condensed milk
- 4 Large egg yolks
- 0.5 cup (120ml) Freshly squeezed Key lime juice
- 1 tbsp Key lime zest
- 1 cup (240ml) Heavy whipping cream
- 2 tbsp Powdered sugar
Instructions:
- Preheat your oven to 350°F (175°C) and line a standard 12-cup muffin tin with paper liners.
- In a medium bowl, combine graham cracker crumbs, granulated sugar, sea salt, and melted butter. Stir until the mixture resembles wet sand.
- Divide the mixture into the 12 liners and press down firmly. <small>Note: Packing it tightly prevents the base from falling apart later.</small>
- Bake the crusts for 5 minutes until fragrant and slightly golden. Let them cool while you make the filling.
- In a medium bowl, whisk 4 egg yolks and 1 tbsp lime zest until smooth and pale yellow.
- Pour in 14 oz sweetened condensed milk and whisk until fully incorporated.
- Slowly pour in 0.5 cup lime juice while whisking gently. The mixture will noticeably thicken.
- Divide the lime custard evenly among the par baked crusts.
- Slide back into the oven for 10 minutes until the edges are set but the centers still jiggle slightly.
- Let the tin cool to room temperature, then refrigerate for at least 3 hours until the filling is firm and cold.
