National Lobster Day is observed worldwide on June 15, celebrating the culinary delight of lobster. While some also recognize it on September 25, the day encourages people to explore various ways to enjoy this seafood, traditionally considered a luxury food. Historically, lobster was viewed as food for the lower classes and was even served in prisons, but its popularity surged in the mid-19th century among New Yorkers and Bostonians. Common cooking methods include boiling, baking, steaming, or grilling, with the lobster roll sandwich being a popular dish. This sandwich typically consists of cooked lobster meat mixed with mayonnaise, Dijon mustard, diced celery, lemon juice, and Old Bay Seasoning, served in hot dog rolls lined with lettuce. National Lobster Day presents a perfect opportunity for seafood lovers to indulge in this delicacy and try new recipes.
