Lemon curd is a delicate custard made from lemon juice, eggs, butter, and sugar. It is used as a sauce/filler for pies, tarts, cakes, and pastries. And sometimes even served as a separate dessert.For me, lemon curd is one of the most powerful flavor combinations. Everything about it is perfect. It has a delicate, smooth texture, acidity that excites the imagination, but is sufficiently balanced by the sweetness of the sugar and an absolutely incredible lemon flavor. I guarantee that once you try it, you will never forget the experience.
