Vinegar Pie

Oven, in the book's wordsA rather quick oven

Ingredients

Directions

The book says “a rather quick oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Make the filling

  1. Combine vinegar and hot water in a bowl.

  2. Mix sugar and flour together, then add to the vinegar mixture.

  3. Stir in the butter and beaten egg.

  4. Cook over hot water until thickened.

  5. Remove from heat and add lemon extract.

Bake

  1. Line pie tins with puff pastry and pour the mixture in.

  2. Bake with an under crust at 350°F (175°C) until set.

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

What each ingredient does

Egg
Binds the filling and helps it set into a sliceable custard as it cooks.
Flour
Thickens the filling so it holds its shape when cut.
Sugar
Sweetens the filling and balances the sharpness of the vinegar.
Vinegar
Provides the tart flavour that defines the pie.
Butter
Adds richness and a smooth mouthfeel to the filling.

The step that matters

Cook over hot water until thickened. The egg and flour thicken the filling gently. Cooking too hot can curdle the egg, leaving a grainy texture, so keep the heat moderate and stir steadily until the mixture coats a spoon.

Swap the lemon
