Step-by-step explanation:
A meringue cookie is a type of dessert made from egg whites and sugar that are whipped together until light and fluffy, then baked until they become crisp and crunchy. They are usually piped into various shapes before baking and can be flavored with extracts or mixed with other ingredients like chocolate chips or crushed nuts. A popular example of a meringue cookie is a French macaron, which consists of two meringue cookies sandwiched together with a filling in between.
A meringue decoration, on the other hand, refers to using meringue as a decorative element on cakes or pastries. This can include piping meringue onto a cake to create intricate designs, such as rosettes, swirls, or flowers. Meringue can also be used to create intricate figurines or sculptures, such as animals or objects, that are then placed on top of a cake or dessert.
