National Buttermilk Biscuit Day is observed worldwide every May 14, celebrating a beloved Southern food staple that gained popularity in the 19th century. This unofficial food day honors the evolution of biscuits from hard, dry European-style baked goods to the soft, fluffy buttermilk biscuits that are now a breakfast favorite in the United States. The transformation was influenced by the availability of chemical leaveners, Southern wheat flour, and buttermilk, which together create a light and airy texture. Traditionally, buttermilk biscuits are served warm for breakfast with various toppings such as butter, honey, or syrup, and are often used in breakfast sandwiches or paired with sausage gravy. Additionally, they can accompany dinner dishes like fried chicken and Southern barbecue, making them a versatile addition to meals, especially during Thanksgiving.
