Key Lime Box

Fresh Key Limes

Key limes are smaller than Persian limes (the dark green ones at every supermarket), more aromatic, more tart, and yellow rather than green when fully ripe. The flavor is what built Florida's most famous dessert: key lime pie, the official state pie since 2006, made with key lime juice, sweetened condensed milk, and egg yolks. Outside of pie, fresh key limes carry cocktails, ceviches, marinades, and any recipe where Persian limes feel too mild. Each box ships by the pound from our family farm partners in Mexico, Central America, and other warm-climate regions where key lime trees thrive (Florida's commercial crop was wiped out by the 1926 hurricane and never fully recovered). Free U.S. shipping covers every key limes delivery, with the Arrive Fresh Guarantee on every box.

Best Fresh Key Limes For...

Authentic Key Lime Pie

The best fresh key limes for key lime pie are the smaller, fully yellow ones, which yield the pale yellow juice the original recipe calls for. One pound makes enough juice for a 9-inch pie.

Margaritas and Cocktails

The best key limes for cocktails are the riper yellow fruits, with stronger aroma and more juice per fruit than green Persians. A few muddled with rum and mint make a far better mojito.

Ceviche and Marinades

The best fresh key limes for ceviche are whichever size matches your batch. The higher acidity cooks fish faster, and the floral aroma carries through the marinade better than standard lime juice would.

Zest and Garnish

The best place to buy key limes for zest and garnish is the 5-pound box. The thin yellow rind grates finer than a Persian peel, with more aromatic oils per gram.
