Sweet, tart, velvety, and versatile, lemon curd is easy to make and has many uses. Fill cakes and pastries, spread it on scones or muffins, or spoon it over desserts.
4 tablespoons unsalted butter, cut into small pieces, room temperature
Instructions
Place a fine mesh sieve over a bowl. Set aside.
In the top pan of a double boiler or a metal bowl, whisk the lemon juice with the sugar and eggs.
Place the bowl over a pan of simmering water (the bottom of the bowl should not touch the water) and cook for 8 to 10 minutes, stirring constantly. When the mixture has thickened to the consistency of yogurt, pour it through the sieve.
Add the lemon zest to the curd and add the butter a few pieces at a time, stirring after each addition.
Pour it into a bowl and place a sheet of plastic wrap directly on the surface to prevent a skin from forming.
Transfer the cooled lemon curd to a jar and refrigerate for up to 2 week. Or freeze the lemon curd in small amounts for up to 1 year.
