National Roast Leg of Lamb Day is observed worldwide on May 7. This unofficial holiday celebrates the culinary tradition of roasting lamb, which is considered one of the best ways to prepare this meat. The day highlights the historical significance of domestic sheep, which were valuable livestock during the Middle Ages, providing wool, milk, skins, and meat. Lamb, mutton, and hogget refer to the meat of sheep at different ages, with lamb being the tender meat from sheep in their first year. On this day, people are encouraged to roast a leg of lamb, often seasoned with rosemary, thyme, oregano, and lemon zest, and served with vegetables and gravy. A stuffed leg of lamb is also a popular choice for a special touch.
