- 1 large lime Lime Zest (Optional, adds extra lime aroma)
- 14 oz Sweetened Condensed Milk (Full‑fat, canned)

Instructions
Process Graham Crackers
Place 1½ packs of Graham crackers in the food processor and pulse until a fine dust forms.
Time: PT2M
Combine Crust Ingredients
Weigh 200 g of the cracker dust, add 40 g powdered sugar and a pinch of kosher salt, whisk to combine, then stir in 100 g melted unsalted butter until the mixture resembles wet sand.
Time: PT5M
Form and Bake Crust
Press the crumb mixture evenly into a 9‑inch pie plate, using your fingers or a flat‑bottomed ramekin to smooth the surface and edges. Bake at 325°F for 15 minutes, then transfer to a wire rack to cool completely.
Time: PT20M
Temperature: 325°F
Prepare Key Lime Curd – Egg Yolks
Separate 3 large egg yolks from the whites. In the stand mixer fitted with the wire whisk, beat the yolks on high speed for about 3 minutes until they become thick, ribbon‑like, and increase slightly in volume.
Time: PT3M
Add Condensed Milk
With the mixer on medium‑high, add the 14‑oz can of sweetened condensed milk and beat for 5 minutes until the mixture is light, pale, and slightly thickened.
Time: PT5M
Incorporate Lime Juice
Reduce mixer speed to low and slowly pour in 2/3 cup fresh key lime juice while the mixer runs. Mix just until combined; the acid will cause the mixture to thicken slightly.
Time: PT1M
Rest Curd
Cover the bowl with plastic wrap and let the curd rest at room temperature for 30 minutes. It will thicken further.
Time: PT30M
Bake Filling
Pour the rested curd into the cooled crust, smooth the top, and bake at 325°F for 25 minutes, or until the edges are set and the center registers 145°F on an instant‑read thermometer.
Time: PT25M
Temperature: 325°F
Cool Pie
Remove the pie from the oven and let it cool on a wire rack to room temperature (about 2 hours). Then wrap tightly in plastic wrap and refrigerate for at least 4 hours, preferably overnight.
Time: PT6H
Whip Cream Topping
In a chilled mixing bowl, combine 1 pint heavy cream, 2 Tbsp granulated sugar, and a dash of vanilla extract. Beat with a whisk or electric mixer until stiff peaks form (about 5 minutes).
Time: PT5M
Pipe and Garnish
Transfer the whipped cream to a pastry bag fitted with a fluted tip and pipe decorative swirls over the chilled pie. Garnish with thin key lime slices and a generous dusting of lime zest.
Time: PT3M
Serve
Slice the pie with a sharp knife, wipe the blade between cuts for clean edges, and enjoy each slice chilled.
Time: PT2M
