Common Questions About Making Key Lime Pie
1. Can I use regular limes instead of Key limes?
Absolutely! Regular (Persian) limes work just fine, but Key limes give that classic tangy kick. If you’re using regular limes, expect a slightly less tart but still delicious pie.
2. Do I really need to bake the pie?
Yes, a quick bake helps the filling set properly and makes the texture silky smooth. No shortcuts here—it’s worth it!
3. Why is my filling too runny?
Oops! This usually happens if it wasn’t baked long enough or if the ingredients weren’t fully combined. Make sure to mix well and bake until the filling is set.
4. Can I use bottled Key lime juice?
Yes! Bottled Key lime juice is a lifesaver when fresh ones aren’t available. Just pick a good-quality brand for the best flavor.
5. How should I store leftovers?
Pop your pie in the fridge, covered, and it’ll stay fresh for up to 3 days. Want to save some for later? It freezes beautifully—just thaw in the fridge before serving!
