This is a recipe that I came up with on my own, but it tastes exactly like the one at Saluda Grade.
1 baked pie shell
½ cup whipping cream
3 tablespoons sugar, divided
8 oz cream cheese, softened
1 teaspoon vanilla extract
2 cups fresh blueberries
In a bowl, beat the whipping cream and 1 tablespoon of sugar until stiff peaks form.
In a larger bowl beat together the rest of the sugar, cream cheese and vanilla extract. Once everything is well combined and the cream cheese is smooth and creamy, slowly fold in the whipping cream. Once everything is combined gently fold in the blueberries.
Pour the filling into a prepared pie shell and chill for at least and hour to allow the pie to set up. Now try to stop yourself from eating the whole thing at once.
