Origin of lemons

While no one knows the exact origin of this unique fruit, the word “lemon” came from the Middle English word “limon” between 1350 and 1400. Sources suggest that this fruit may have come from the Northwest of India, as people in this region have been cultivating it for over 2,500 years. Sometime after 100 CE, Arab traders introduced this citrus fruit to Africa and the Middle East. Historians believe that the fruit was introduced to Southern Italy around 200 CE. Up until the 10th century, people didn’t see this citrus fruit as food and only cultivated it for decoration and ornamental purposes. 

These fruits made their way into Spain in the 1100s, which the Arabs were also responsible for. Later, crusaders from Palestine brought this fruit to the remainder of Europe, where the first use of it in food was in the 15th century. Christopher Columbus would later introduce this fruit to the new world when he brought the seeds into Hispaniola. Spanish conquest also played a significant role in spreading this fruit around the world. 

In the 18th century, people in California planted this fruit and further south in Florida locals started using it for culinary purposes. The cultivation of this fruit experienced tremendous growth in Florida and California during this period. In 1953, the need for frozen concentrate and natural cold-press oil sparked up the production of this citrus fruit again. Today, this fruit has found its way into many dishes and treats.
