In a medium saucepan, combine all the ingredients together and gently whisk on low heat until the butter melts and the curd starts to thicken. (the lemon curd should be able to coat the back of a wood spoon and can hold the shape when a line is drawn through it)
Remove the saucepan from the heat and strain the lemon curd into a glass bowl and cover the curd using plastic wrap and pressing it onto the top of the curd to prevent it from forming a crust.
Allow the lemon curd to cool at room temperature and then place in the refrigerate to thicken and set completely before using.
