Meringue is a light and fluffy dessert made primarily from whipped egg whites and sugar. When beaten together, the egg whites become airy and form stiff peaks, which gives meringue its signature texture. It can be baked until crisp or used as a topping for pies, like the classic lemon meringue pie, where it adds a sweet and airy contrast to the tart filling. There are different types of meringue, including French, Italian, and Swiss meringue, each varying in preparation methods. Meringue is not only delicious but also versatile, often used in various desserts, such as pavlova and macarons, showcasing its ability to elevate sweet treats.
