Optional: Sweetened whipped cream and lemon slices for garnish
Instructions
Prepare a baked pie crust according to your recipe instructions and let cool completely.
In a medium saucepan, combine sugar, cornstarch, milk, egg yolks, butter and lemon peel. Cook over medium heat, stirring constantly, until the mixture is thick and bubbly. Cook and stir for two minutes more. Remove from the heat and stir in the lemon juice.
Pour the mixture into a large mixing bowl and immediately cover with plastic wrap, pushing down and making sure that the plastic is touching the top of the lemon curd so that a skin doesn’t form. Let cool to room temperature.
When the lemon curd has cooled, gently stir in the sour cream and blueberries, taking care not to break the blueberries. When mixed completely, pour into your baked pie crust.
Cover and chill at least 4 hours.
If desired, serve with sweetened whipped cream and garnish with lemon slices.
