Arugula has been grown by humans since ancient Roman times. In fact, the ancient Romans first used it as a medicinal herb and an aphrodisiac. Over time, it was incorporated into the cuisine of the region and today, it is closely associated with Italian cooking. Although it is frequently included in spring salad mixes, arugula is not a type of lettuce, rather, it is closely related to cabbage and mustard greens. This explains arugula’s characteristic peppery flavor. Arugula is generally available in grocery stores year-round, but is in its peak season in early spring and fall. It is also known as rocket, rucola, and roquette. Today, it is frequently used in Italian recipes but is also widely enjoyed throughout the world in salads and other dishes.
