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
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 plain tin cake or pie mold generously.
Roll out the paste thinly.
Place the mold on the paste.
Trim to size.
Cover the bottom of the mold with the paste.
Cut a band for the sides.
Press the band on, moistening the edges with water.
Make the apple marmalade
In a pot, boil the apples, powdered sugar, lemon juice, fresh butter, and cinnamon over low heat.
Increase the heat until smooth and dry.
Cool the marmalade completely before filling the mold.
Assemble and bake
Roll out a cover for the tart.
Lay it over the marmalade without touching it.
Seal the edges.
Trim off excess paste.
Sprinkle with powdered sugar.
Bake until golden.
Preheat the oven to 350°F (175°C).

Sugar and cinnamon barely smell alike, yet cooks put them together in 30,779 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Provides richness and tenderness to the pastry as it is worked into the flour.
- Flour
- Forms the structure of the pastry paste and holds the tart shape.
- Egg yolks
- Add richness and help bind the paste into a smooth, firm dough.
- Apples
- Supply the main filling and fruity flavor once cooked into a marmalade.
- Powdered sugar
- Sweetens the apple marmalade and helps it cook to a thick, smooth texture.
- Lemon juice
- Adds acidity that brightens the sweet apple filling.
The step that matters
Cook the marmalade until smooth and dry. Apples hold a lot of water. Cooking them down until thick and dry keeps the filling from soaking the pastry and making the bottom soggy. Cooling it completely before filling also prevents the pastry from softening and the cover from melting into the filling.
Swap the apple
How well each one fits the dish's main ingredients (butter, flour, egg, sugar, lemon, cinnamon):
