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.
Mix in the egg yolks.
Add enough water to form a firm, smooth paste.
Line the mold
Butter a plain tin cake or pie mold generously.
Roll out the paste thinly.
Place the mold on the paste and trim to size.
Cover the bottom of the mold with the paste.
Cut a band for the sides.
Press the band around the edges, moistening with egg or water to seal.
Make the filling and bake
In a pot, boil the apples with the 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.
Roll out a cover for the tart.
Lay the cover over the cooled marmalade.
Seal the edges.
Trim any excess paste.
Sprinkle with powdered sugar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creates a tender, crumbly texture in the pastry and rich flavor in the filling.
- All-purpose flour
- Forms the structure of the pastry paste.
- Egg yolks
- Add richness and bind the pastry into a smooth dough.
- Apples
- Cook down into the fruit filling, providing the body and flavor of the tart.
- Powdered sugar
- Sweetens the apple filling and helps it thicken as it is reduced.
- Lemon juice
- Adds acidity that brightens the sweetness of the apples.
The step that matters
Increase the heat until smooth and dry. The apple mixture must cook down until it is thick and free of excess liquid. If it stays wet, the filling will be runny and may soak the pastry base.
