What is "lemon curd"?

Lemon curd is a sweet and tangy spread made from lemon juice, sugar, eggs, and butter. It has a smooth and velvety texture with a bright and refreshing flavor that is both sweet and tart. Lemon curd is commonly used as a filling for cakes, tarts, and pastries, adding a burst of citrusy flavor and a creamy consistency to baked goods. It can also be spread on toast, scones, or biscuits, or used as a topping for yogurt or ice cream.
