Ingredients
- Vanilla wafer crumbs: Create a buttery, crisp crust that adds texture and a hint of vanilla flavor.
- Butter: Holds the crust together and gives it a rich, buttery taste.
- Lemon gelatin: Provides the bright lemon flavor while helping the filling set into its signature fluffy texture.
- Boiling water: Dissolves the gelatin completely so the filling is smooth.
- Granulated sugar: Sweetens the filling and balances the tartness of the lemon juice.
- Lemon juice: Adds citrus flavor, making the dessert taste bright and refreshing.
- Chilled evaporated milk: The secret to the airy, mousse-like filling. When whipped, it creates the light, fluffy texture that gives this dessert its name.
- Salt: A small amount enhances the sweetness and brings out the lemon flavor.
Directions
Step 1: In a large bowl, dissolve the lemon gelatin in the boiling water, stirring until completely dissolved.
Step 2: Stir in the sugar and lemon juice until the sugar is dissolved. Refrigerate until the mixture is slightly thickened but not fully set, about 30 to 45 minutes.
Step 3: Meanwhile, combine the crushed vanilla wafers and melted butter. Press the mixture evenly into the bottom of a 9 x 13-inch baking dish to form the crust.
Step 4: In a separate large bowl, beat the chilled evaporated milk with the salt on high speed until light and fluffy. Gently fold the whipped evaporated milk into the slightly thickened gelatin mixture.
Step 6: Spread the filling evenly over the prepared crust. Sprinkle with additional vanilla wafer crumbs, if desired. Refrigerate until thoroughly chilled and set, at least 4 hours or overnight before serving.
