It’s so easy to make delicious homemade lemon curd – you need just four ingredients and less than 30 minutes to make this bright, creamy spread, which also happens to be the best filling for my lemon curd napoleons or raspberry and lemon tartlets.
Combine yolks, lemon zest, lemon juice, and sugar in a small saucepan. Whisk to combine.
Cook over low to medium heat, stirring constantly with a wooden spoon, making sure to stir sides and bottom of pan. Cook until mixture is thick enough to coat back of wooden spoon, about 5 minutes.
Remove saucepan from heat. Add butter, one piece at a time, stirring with the wooden spoon until consistency is thick and smooth.
Transfer mixture to a bowl. Lay a sheet of plastic wrap directly on the surface of the curd to avoid a skin from forming; wrap tightly.
Refrigerate until firm and chilled, at least 1 hour.
Tart Shells
Preheat oven to 350 degrees.
Add the flour, sugar and salt to a stand mixer with paddle attachment. Beat on low to combine. Add cold butter, beat until butter is the size of small peas with the flour mixture. This can also be done in a food processor.
With the mixer on, slowly add the ice water until dough forms and is combined.
Transfer dough to a lightly floured countertop, kneading a couple times to combine. Divide dough in half, flatten slightly and wrap tightly with plastic wrap.
Refrigerate for 1 hour before using.
When ready to use, roll out the dough. Cut individual circles for each tart shell using a glass or pastry cutter. Push each circle into a greased cupcake tray.
Bake empty tarts for 5 - 10 minutes or until a light golden color. Allow to cool.
Fill each tart shell with lemon curd and top with a raspberry.
