Equipment you’ll use
To create this key lime pie, you’ll need a few essential kitchen tools:
- 9-inch pie pan
- Flat-bottomed measuring cup
- Mixing bowls
- Whisk
- Wire rack
- Zester or grater
Ingredients
- 1 ½ cups (180 g) graham cracker crumbs
- 2 tablespoons (25 g) white sugar
- 5 tablespoons (70 g) unsalted butter, melted
- 3 large egg yolks
- 1 ⅓ cups (396 g) sweetened condensed milk (about 1 can)
- ½ cup (120 ml) key lime juice (about 25 key limes)
- 1 tablespoon key lime zest (from about 3 key limes)
- 1 tablespoon full-fat sour cream
- Pinch of salt
- Whipped cream, for topping (optional)
Step-by-step instructions
- Preheat your oven to 350°F (175°C). Combine the graham cracker crumbs, sugar, and melted butter in a bowl.
- Firmly press the mixture into a 9-inch pie pan using a flat-bottomed cup. Bake for 11 minutes, then set aside to cool.
- Lower the oven temperature to 325°F (160°C). In another bowl, whisk together the egg yolks, sweetened condensed milk, key lime juice, zest, sour cream, and salt until smooth.
- Pour the filling into the cooled crust, and bake for about 20 minutes, or until the center slightly jiggles while the edges are set.
- Allow the pie to cool on a wire rack for 2 hours. For the best texture, refrigerate it overnight.
- Before serving, top with whipped cream and garnish with lime slices.
Tips, troubleshooting, and common mistakes
- Crust Too Crumbly: Ensure you’ve pressed the crust firmly using the measuring cup. If it’s falling apart, add a little more melted butter.
- Runny Filling: If your filling is too runny after baking, it might need more time in the oven. Look for a slight jiggle in the center.
- Overbaked Crust: Always keep an eye on your crust while pre-baking to avoid burning. It should be lightly golden.
Pairing ideas and variations
Key lime pie goes beautifully with a side of freshly whipped cream. You can also try pairing it with a tropical fruit salad for a vibrant twist. For variations, consider adding coconut flakes to the crust for a subtle island flavor or drizzle with a raspberry coulis to add a hint of color and contrast.
