National Lemon Meringue Pie Day is celebrated every year on August 15, primarily in the United States. This day honors one of America’s favorite desserts, the lemon meringue pie, which consists of a shortcrust or shortbread pastry crust, lemon-flavored custard, and a fluffy meringue topping. The origins of lemon custard pies date back to Medieval times, while the meringue was developed around the 17th century. The combination of these elements in pie form appeared in the 19th century, with the first recorded recipe attributed to Alexander Frehse from Suisse romande. To celebrate, people often enjoy a slice of this delicious pie, either homemade or purchased from local bakeries.
