Frequently Asked Questions

Got questions about making Refreshing Authentic Key Lime Pie with Graham Cracker Crust? Here are chef-tested answers, storage advice, and easy substitutions.

Do I need real Key limes, or can I use Persian limes?

Authentic Florida Key limes are smaller, yellower, and more aromatic with intense tartness. Bottled Nellie & Joe's Key Lime Juice works well, or you can substitute fresh regular Persian lime juice mixed with 1 tablespoon of fresh lemon juice.

Why is Key lime pie baked if the lime juice curdles the milk?

While acid thickens the egg yolk and sweetened condensed milk filling, baking for 12 to 15 minutes pasteurizes the egg yolks and sets the custard so it slices cleanly while retaining its bright citrus flavor.

How do I make a sturdy graham cracker crust that doesn't crumble?

Mix graham cracker crumbs with melted butter and sugar, then firmly press into the pie dish using the flat bottom of a measuring cup. Pre-bake the crust at 350°F (175°C) for 8 minutes before filling.

How long should Key lime pie chill before serving?

Chill in the refrigerator for at least 4 to 6 hours, ideally overnight. Serve cold topped with freshly whipped cream and thin lime wheels.
