This classic lemon curd tart recipe is a delightful dessert that combines a buttery shortcrust pastry with a tangy and creamy lemon curd filling. The pastry is made with flour, butter, sugar, and a pinch of salt, while the lemon curd is made with fresh lemon juice, sugar, eggs, and butter. The tart is baked until the pastry is golden and the curd is set. Serve it chilled with a dollop of whipped cream for a refreshing and indulgent treat.
