- 3 eggs, separated
- 1 (9 inch) unbaked single pie crust
- 3 cups chopped rhubarb
- 1 cup white sugar
- 1 cup half-and-half
- 2 tablespoons all-purpose flour
- 1 pinch salt
- 1/4 cup white sugar
- 1/4 teaspoon cream of tartar
- Preheat oven to 350 degrees F (175 degrees C).
- Place egg yolks into a large bowl; place egg whites in a separate glass or metal bowl.
- Fit pie crust into a 9-inch pie dish. Spread rhubarb into bottom of crust. Whisk 1 cup sugar, half-and-half, flour, and salt into egg yolks until smooth. Pour mixture over rhubarb.
- Bake in the preheated oven until pie crust is browned and filling is set, 50 to 60 minutes.
- Beat egg whites until stiff using an electric mixer; gradually beat 1/4 cup sugar and cream of tartar into egg whites to make a glossy meringue. Spoon meringue over pie filling, going right to the edge of the crust and covering all the filling. Use a spoon or spatula to make decorative swirls in the meringue.
- Return pie to oven and bake until meringue is lightly browned, 10 more minutes. Best served slightly warm.
