Lemon pie, a classic dessert known for its tangy and sweet flavors, has been a staple in many cuisines around the world. The traditional lemon pie recipe typically includes a meringue topping, which adds a nice texture and aesthetic to the dish. However, some recipes choose to omit the meringue, resulting in a filling-only lemon pie. This variation raises an important question: does lemon pie without meringue need to be refrigerated? In this article, we will delve into the world of lemon pie and explore the factors that determine its storage requirements.
Understanding Lemon Pie
To answer the question of whether lemon pie without meringue needs to be refrigerated, it is essential to understand the composition of the pie itself. A traditional lemon pie consists of a filling made from lemon juice, sugar, eggs, and butter or cream, baked in a pastry crust. The filling is typically rich and dense, with a high acidity level due to the lemon juice. The acidity helps to preserve the filling to some extent, but it is not enough to guarantee the pie’s safety at room temperature.
