Instructions
Follow each step in order. The directions below are written so a beginner can understand what to do, what to look for, and when to move on to the next step.
- Step 1.Heat the oven to 350°F and mix graham crumbs, melted butter, and sugar until the crumbs feel evenly moistened like damp sand.
- Step 2.Press the crumb mixture firmly into the bottom and sides of a 9-inch pie plate, using a cup to compact the crust evenly.
- Step 3.Bake the crust for 8 minutes until fragrant and lightly darker, then cool it while keeping the oven on for the filling.
- Step 4.Whisk egg yolks until slightly thickened, then whisk in sweetened condensed milk, Key lime juice, and lime zest until smooth.
- Step 5.Pour the filling into the warm crust and spread it level so the pie bakes evenly and slices cleanly after chilling.
- Step 6.Bake for 12 to 15 minutes until the filling is set around the edges and just barely trembles in the center.
- Step 7.Cool to room temperature, then refrigerate for at least 4 hours so the citrus custard becomes cold and sliceable.
- Step 8.Whip cream with powdered sugar, dollop or pipe it on the chilled pie, and garnish with lime slices immediately before serving.
