Vinegar Pie

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the filling

  1. Cream together sugar, egg yolks, flour, butter, and a little water in a bowl.

  2. Boil 1 cup of water with 3 tablespoons of vinegar in a saucepan.

  3. Add the creamed mixture and 1 teaspoon of lemon juice to the boiling water, then pour the filling into a pre-baked pie crust.

Top and bake

  1. Beat the egg whites until stiff and spread over the filling.

  2. Brown the pie in a 350°F (175°C) oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg yolks
Thicken the filling and add richness as they set with the heat.
Flour
Thickens the creamy filling so it holds its shape when cut.
Butter
Adds fat for a smooth, rich texture in the filling.
Vinegar
Adds sharp acidity that balances the sweetness of the sugar.
Egg whites
Whipped into a stiff topping that browns in the oven.

The step that matters

Adding the creamed mixture to the boiling water. Flour-thickened fillings need to be stirred while they heat so the starch swells evenly and does not clump or stay raw-tasting. Adding the mixture to a rapidly boiling liquid can also cause lumps, so the filling should be whisked as it thickens.
