Apply the meringue to the filling that has cooled slightly.
The easiest method of applying meringue is to use a rubber spatula and simply pile it on top. Make sure you “seal” the topping all the way to the edge of the pie so it touches the crust. This will help keep it from shrinking.
After your topping is added, you can leave it as is. It will harden slightly as it sits. Or bake at 425°F/220°C for 4–5 minutes, until lightly browned.
Allow the pie to cool completely before refrigerating, then chill for at least 3 hours before serving.
