This lemon curd tart is a delightful dessert that combines the tangy flavor of lemon curd with a buttery crust. The tart shell is made with a combination of flour, butter, and sugar, which is then filled with a smooth and creamy lemon curd. The tart is baked until the curd is set and the crust is golden brown. Serve it chilled with a dollop of whipped cream for a refreshing and indulgent treat.
