蛋挞, or "egg tart," is a popular pastry originating from Cantonese cuisine. It features a flaky crust filled with a creamy custard made primarily from eggs, milk, and sugar. The tart is typically baked until the custard is set and the top is slightly caramelized, giving it a rich flavor and smooth texture. This delightful treat is commonly found in dim sum restaurants and bakeries across China and other regions influenced by Cantonese culture. Variations of the egg tart exist, including the Portuguese version known as "pastel de nata," which has a slightly different flavor profile and preparation method.
