Why it works: Apple and cinnamon are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 5,598 recipes. Both carry methyl cinnamate, which smells strawberry. The science ↓
Apple Cake, or German Tart
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 pastry
Preheat the oven to 350°F (175°C).
In a bowl, work together the butter and flour until they resemble fine crumbs.
Add a pinch of salt, egg yolks, and enough water to form a firm, smooth paste.
Butter a pie mold.
Roll out the paste thinly.
Trim the paste to fit the mold, covering the bottom and sides.
Moisten the edges with water or egg.
Make the filling
In a pot, combine apples, sugar, lemon juice, fresh butter, and cinnamon.
Cook over low heat.
Increase heat until smooth and dry.
Cool the marmalade completely before filling the mold.
Assemble and finish
Roll out a cover for the tart.
Place the cover over the filled mold without touching the filling.
Seal the edges.
Trim excess paste.
Sprinkle with pounded sugar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and tenderness to the pastry and a smooth, buttery flavor to the filling.
- Flour
- Forms the structure of the pastry paste once mixed with water and egg yolks.
- Egg yolks
- Add richness and help bind the pastry into a firm, workable paste.
- Apples
- Provide the bulk of the filling, which cooks down into a thick, spreadable marmalade.
- Sugar
- Sweetens the filling and helps it thicken as it cooks down.
- Lemon juice
- Adds acidity that brightens the sweetness of the apples.
The step that matters
Cool the marmalade completely before filling the mold. Cooking the apples, sugar and butter down until smooth and dry thickens them. Filling the pastry while the marmalade is still hot can soften the crust and make the filling run, so it should cool first.
