FAQs
Can I use regular limes instead of key limes?
Yes. While key limes have a more intense, floral flavor, regular limes can work in a pinch. For best results, use fresh juice and add a bit of lemon to mimic key lime brightness.
What’s the difference between key lime juice and lime juice?
Key lime juice is more tart and aromatic than regular lime juice. It also has a slightly yellow color, contributing to the pie’s traditional look.
Can I use bottled juice?
Absolutely. Bottled key lime juice is a pantry staple and works well when fresh key limes aren’t available. Look for high-quality brands with 100% juice.
Why is my key lime pie runny?
This usually means it wasn’t baked long enough or didn’t chill properly. Make sure the center jiggles slightly when baked and refrigerate for at least 3 hours.
Is it okay to skip the whipped cream topping?
Yes, but the whipped topping adds balance to the tart filling. For a richer finish, try meringue or sweetened Greek yogurt.
How do I know when the pie is done baking?
The edges should be set, and the center should jiggle slightly but not slosh. Overbaking can cause cracks.
Can I make key lime pie without eggs?
Yes. Use cornstarch or a vegan egg replacer, though the texture will be slightly different. Sweetened condensed coconut milk helps it set.
