Tips

Tip 1

If the pie crust puffs up during initial baking, gently press it down with the bottom of a metal measuring cup while still warm.

Tip 2

Make sure to refrigerate the pie for the full time specified - this ensures the custard filling sets properly and makes clean slicing easier.

Tip 3

Add the strawberry topping just before serving to prevent the berries from releasing too much juice onto the whipped cream.
