Lime pie is a dessert that consists of a sweet and tangy filling made from limes, sugar, and sometimes eggs. The filling is typically poured into a graham cracker or pastry crust and chilled before serving. Lime pie can be either frozen or unfrozen, depending on the recipe used. It's a popular dessert in many countries, including Mexico, where it's known as "pastel de limón," and the Philippines, where it's called "lemon pie."
