The Realtor'S Easy Lemon Curd (Lemon Filling) - cooking recipe

Ingredients

1 cup sugar
4 tablespoons cornstarch
1/2 teaspoon salt
1 cup water
1/2 cup lemon juice
2 tablespoons butter
3 drops yellow food coloring (optional)
1/2 teaspoon lemon zest

Preparation

Mix all the ingredients together in a heavy bottom sauce pan. I shake the water and cornstarch together in a jar first and then add them to the pan to avoid lumps.
Bring to a rolling boil and boil 1 minute, stirring constantly.
Chill or cool before using.
