A lemon tart is a delicious dessert made with a crisp pastry crust filled with a smooth and tangy lemon custard. The filling typically consists of fresh lemon juice, sugar, eggs, and butter, creating a balance of sweetness and acidity. Lemon tarts are often garnished with powdered sugar or whipped cream for added flavor and presentation. This dessert is popular in many cultures and can be served at various occasions, from casual gatherings to formal events. Pastry chefs often experiment with different variations, such as adding meringue on top or incorporating other citrus flavors for a unique twist.
