The answer to the most popular pastry will depend not only on where you live but also whether you are looking for a sweet or savory pastry. For example, if you are looking to eat a sweet-filled pastry with your morning coffee, eclairs (choux pastry) are a popular choice, especially in France. In North America, the flaky pastry that forms the base of sweet fruit pies like a classic apple pie, or savory hand pies like empanadas might be the most popular.
