Chef’s Tips

• Real key limes are smaller and more floral, but ordinary limes make an excellent pie. Bottled juice does not.
• Zest before juicing. It is nearly impossible afterwards.
• The pie needs a full overnight chill to reach its proper sliceable texture.

Pairing Suggestions

• A cold beer, oddly enough, or a glass of Prosecco
• Serve after seafood or barbecue
• Follow with strong coffee

Storage & Reheating

Refrigerate up to 3 days. Add the cream topping on the day of serving. Freezes 1 month without the cream.
