Old-fashioned pineapple sour cream pie features a creamy pineapple filling and billowy meringue. It is the perfect mix of tangy and sweet. This dessert is going to become a new favorite.
Preheat oven to 350℉ and make sure you have a baked pie crust ready to go.
Stir sugar and flour together in a large saucepan.
Add the pineapple (including the juice) and sour cream. Mix until combined.
Cook over medium heat, stirring frequently, until thickened and bubbly. Reduce heat to low and cook 2 minutes longer. Remove from heat.
In a small bowl, whisk the egg yolks.
Stir a small amount of the hot pineapple mixture into the egg yolks. Return the mixture with the egg yolks to the pan with the remaining filling. Stir vigorously to combine.
Put back over medium heat and cook, stirring continuously, until it has boiled for 2 minutes. Remove from heat and set aside.
In a medium mixing bowl, beat the egg whites, vanilla, and cream of tartar on medium speed until it forms soft peaks.
Gradually add the sugar, beating between additions until it has all been incorporated.
Beat on high until stiff glossy peaks form.
Pour warm pie filling into a baked pastry shell.
Spread the meringue over the pie filling, being sure to go all the way to the edges of the crust.
Bake at 350℉ for 15-18 minutes or until the meringue is golden brown.
Cool on a wire rack for one hour before transferring to the refrigerator to chill, at least 3 hours.
Refrigerate leftovers.
Notes
If you would like to make this a no-bake pie, just use a graham cracker crust for the base. Chill the pie with the filling and top with whipped cream instead of meringue.
