Lemon curd is a sweet and tangy spread that is made with only five ingredients and a bold burst of lemon flavor. It's the perfect addition to any dessert.
Combine 75 grams of the butter, 64 grams of the sugar, the lemon zest and lemon juice in a small saucepan and bring to a boil over medium heat. Stir gently to dissolve the sugar.
In a bowl combine egg yolks with the remaining sugar. Temper by slowly adding about ⅓ of the lemon juice mixture. Stirring constantly with a whisk.
Return the tempered egg mixture back to the saucepan. Continue cooking, whisking constantly until mixture returns to a boil.
Stir in the remaining butter until the butter melts.
Strain the curd through a fine-mesh strainer. Cover with plastic wrap placed directly on the surface of the curd.
