What is the origin of Key lime, and how does it differ from other lime varieties?
The Key lime, also known as the Mexican or West Indian lime, is a small, acidic lime that originated in the Indo-Malayan region. It was introduced to the Florida Keys by Spanish settlers in the 16th century and became a staple crop in the region. Key limes are distinct from other lime varieties, such as the Tahiti or Bearss lime, due to their unique flavor profile and aroma. They have a higher acidity level and a more complex flavor profile, which is often described as a combination of sweet and tart notes.
The unique characteristics of Key limes can be attributed to the region’s subtropical climate and the soil conditions in which they are grown. The Florida Keys’ warm and humid climate, combined with the region’s limestone soil, contribute to the Key lime’s distinctive flavor and aroma. In contrast, other lime varieties are often grown in different regions with varying climate and soil conditions, resulting in distinct flavor profiles. For example, Tahiti limes are often grown in California and have a milder flavor, while Bearss limes are grown in Mexico and have a sweeter taste.
