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 says “a moderately brisk oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the crust
In a bowl, work together the butter and flour until they resemble fine crumbs. Add a pinch of salt, then mix in the egg yolks and enough water to form a firm, smooth paste.
Butter a pie mold and roll out the paste thinly. Trim the crust to fit the mold, covering the bottom and sides.
Moisten the edges and press a thin band of paste around the sides to prevent separation.
Make the filling
In a pot, boil the apples, sugar, lemon juice, butter, and cinnamon until smooth and dry.
Let the apple mixture cool completely.
Assemble and bake
Fill the mold with the cooled apple mixture and roll out a cover for the tart.
Lay the cover over the filling without touching it, then trim off excess paste.
Decorate the top with thinly cut leaves made from the excess paste and sprinkle with pounded sugar.
Bake in a preheated oven at 350°F (175°C) for 1 hour. If needed, return to the oven for a few more minutes to color the sides.

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
- Adds richness and tenderness to the crust and moisture to the apple filling.
- Flour
- Provides the structure that holds the crust together.
- Egg yolks
- Bind the dough and add richness and color to the crust.
- Apples
- Form the main filling, softening and thickening as they cook down.
- Pounded sugar
- Sweetens the filling and browns the surface of the tart.
- Ground cinnamon
- Adds warm aroma to the apple filling.
The step that matters
Let the apple mixture cool completely. Filling a crust with hot apples melts the butter in the paste, so the base turns soggy and the crust can slump or separate from the sides during baking.
