National Quiche Lorraine Day is observed worldwide on May 20 each year, celebrating the popular variant of quiche known as Quiche Lorraine. This savory tart, which features a pastry crust filled with egg and cream custard, is typically made with ingredients such as cheese, vegetables, meat, or seafood. The name "quiche" is derived from the German word "Kuchen," meaning "tart" or "cake," although it is regarded as a quintessential French dish. Quiche Lorraine, named after the French region of Lorraine, originally consisted of eggs, cream, and lardons in a buttery crust, with modern recipes often substituting bacon and incorporating various cheeses. While many varieties of quiche exist, Quiche Lorraine remains a staple in French cuisine. People celebrate this day by enjoying slices of quiche, which can be served hot or cold, often paired with salad and white wine.
