Ingredients

8 large egg yolks 

3/4 cup sugar 

1/2 cup plus 2 tablespoons, freshly squeezed lemon juice 

3 tablespoons grated lemon zest 

1 pinch of salt 

1 teaspoon potato starch 

8 tablespoons (1 stick) margarine, cut into 12 pieces 

Preparation

Whisk together egg yolks, sugar, lemon juice, lemon zest, salt, and potato starch in a medium saucepan. Whisk over medium heat until thick, about 10 minutes. Remove saucepan from heat. Stir in margarine, one piece at a time, until all of the pieces have been fully incorporated. Transfer the lemon curd to a bowl, and lay a piece of plastic wrap on the surface to prevent a skin from forming.
