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
Make the pastry
In a bowl, work together the butter and flour until they resemble fine bread crumbs.
Add a pinch of salt, then mix in the egg yolks and enough water to form a firm, smooth paste.
Line the mold
Butter a plain tin cake or pie mold.
Roll out the paste thinly and line the mold with it. Cut a band of paste for the sides, moisten the edge of the band and press it to the bottom crust.
Make the filling
In a pot, boil the apples, sugar, lemon juice, fresh butter, and cinnamon over low heat. Increase the heat until the mixture becomes smooth and dry.
Cool the marmalade completely before filling the mold.
Cover and finish
Roll out a cover for the tart. Place the cover over the filled mold without touching the marmalade. Seal the edges of the cover.
Trim any excess paste and 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
- Enriches the paste and adds richness and tenderness to the crust.
- Flour
- Forms the structure of the paste that holds the crust together.
- Egg yolks
- Add richness and help bind the paste into a smooth dough.
- Apples
- Provide the bulk of the filling, becoming soft and cooking down into a thick marmalade.
- Pounded sugar
- Adds sweetness and helps the filling thicken as it cooks down.
The step that matters
Cool the marmalade completely before filling the mold. Filling the crust with hot marmalade can soften the pastry from below and melt the butter, so the crust may turn soggy or lose its shape.
