Zwieback 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

Preheat the oven to 350°F (175°C).
In a bowl, combine the grated zwieback, chopped apples, malt extract, sugar, almond meal, salt, vanilla, and nutmeg, and mix well until all ingredients are combined.

Assemble and bake

Pour the mixture into a pie dish lined with a crust.
Cover with a second crust and seal the edges.
Bake for 30-40 minutes or until the crust is golden brown.

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

What each ingredient does

Grated zwieback: Forms the bulk of the filling and absorbs moisture as it bakes, giving body to the pie.
Tart apples: Provide moisture and a tangy acidity that balances the sweetness of the filling.
Malt extract: Adds sweetness and a toasty, caramel-like flavour, and helps the crust brown.
Sugar: Sweetens the filling and promotes browning of the crust during baking.
Almond meal: Adds fat and a nutty flavour, and gives the filling a tender, slightly dense texture.
