FAQ

Can I use regular limes instead of key limes?

Yes, regular lime juice works well though the flavor will be slightly less tart and aromatic than traditional key limes.

How long does this pie keep in the freezer?

The pie can be frozen for up to 1 month when properly wrapped, though the texture may be slightly firmer when thawed.

Can I make this without the mango?

Absolutely, simply omit the mango for a classic key lime pie or substitute with other fruit like strawberries or peaches.
