History
The pound cake originated in Europe during the 18th century, named for its simple ratio: one pound each of flour, butter, sugar, and eggs. Key limes, smaller and more aromatic than Persian limes, have been cultivated in the Florida Keys since the 16th century. This fusion recipe likely emerged in the mid-20th century as home bakers sought to add citrus brightness to traditional pound cakes, celebrating Florida’s signature fruit.

Formation (Cake Structure)
The high fat content (butter + sour cream) and low gluten development (minimal mixing) create the dense, fine crumb signature of pound cakes. Key lime juice provides acidity, which reacts with baking soda for gentle lift, while eggs add structure. Zest disperses essential oils evenly for consistent flavor.
