FAQs

Can I use regular limes instead of key limes?

Yes, but key limes have a more intense and slightly floral flavor. If using regular limes, add a bit more zest for extra brightness.

How do I know when the pie is done baking?

The center should be just set but still slightly jiggly when you gently shake the pan. It will firm up as it chills.

Why does my key lime pie have a bitter taste?

Using too much lime zest can cause bitterness. Stick to 1 teaspoon for a balanced flavor.

Can I use bottled key lime juice?

Yes, bottled key lime juice works well and is a convenient alternative to fresh key limes.

Should I blind-bake the crust longer for a crispier texture?

If you prefer a crunchier crust, bake it for an extra 2-3 minutes before adding the filling.

Can I make this pie ahead of time?

Yes, key lime pie is a great make-ahead dessert since it needs time to chill. Prepare it the night before serving.

What’s the best way to slice key lime pie cleanly?

Use a sharp knife dipped in hot water and wiped clean between slices for neat, even cuts.

Is key lime pie supposed to be served cold?

Yes, it’s best served chilled to maintain its creamy texture.

Can I make a dairy-free version of this pie?

Yes, use sweetened condensed coconut milk instead of regular condensed milk, and replace the whipped cream with a dairy-free alternative.
