Elderberry and Apple 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.

Prepare the filling

  1. Preheat the oven to 350°F (175°C).

  2. In a mixing bowl, combine the elderberries, apple sauce, sugar, and flour.

  3. Add the beaten egg yolks and mix well.

Bake and finish

  1. Pour the mixture into an unbaked pie shell.

  2. Dot the top with butter.

  3. Bake until the filling is set and cooked through.

  4. Make a meringue with the egg whites and spread it over the pie.

  5. Return the pie to the oven for about 12 minutes to set and brown the meringue.

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

What each ingredient does

Elderberries
Provide the main fruit flavor and bulk of the filling.
Flour
Thickens the juices so the filling sets rather than running.
Eggs
Set the filling when baked and form the meringue topping.
Apple sauce
Adds tartness and moisture while contributing pectin to help the filling set.
Sugar
Sweetens the filling and helps the meringue stay stable and brown.
Butter
Adds richness and fat to the filling's flavor and texture.

The step that matters

Baking until the filling is set. Flour and egg proteins thicken as they heat, so the filling must reach a full set before the meringue goes on. Underbaking leaves a runny, soupy pie, while overbaking can make the custard-like filling weep or crack.

Swap the apple

How well each one fits the dish's main ingredients (flour, egg, sauce, butter, sugar):

  4. Applethe original

Fit is the average pairing score against flour, egg, sauce, butter, sugar. Candidates are from the same food group and used in at least 100 recipes.
