Make the hull:
Preheat stove to 350°F (175°C).
In a bowl, combine graham saltine scraps, sugar, and dissolved butter.
Press the blend immovably into the foot and sides of a 9-inch pie dish.
Prepare for 8 minutes, at that point set aside to cool.
Get ready the filling:
In a blending bowl, whisk together egg yolks and sweetened condensed drain until smooth.
Include key lime juice and lime get-up-and-go, blending until completely combined.
Pour the filling into the cooled hull and spread equally.
Heat the pie:
Prepare at 350°F for 15 minutes, until the filling is fair set but still somewhat jiggly within the center.
Expel and let cool at room temperature for 30 minutes.
Chill and set:
Exchange pie to the fridge and chill for at slightest 3 hours (ideally overnight) to permit the filling to firm up.
Make the whipped topping:
Beat overwhelming cream and powdered sugar together until delicate crests frame.
Spread or pipe over chilled pie some time recently serving.
Embellish with lime cuts or get-up-and-go in case craved.
