Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
German Apple Cake
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.
Prepare the batter
Preheat the oven to 350°F (175°C).
Sift together the flour, salt, and baking powder.
Work the butter into the dry ingredients.
Beat the egg, add the milk, and stir into the mixture.
Spread the batter in a well-buttered shallow pan.
Top and bake
Press the apples down into the dough.
Sprinkle the apples with dried currants and the edges with powdered sugar.
Bake until the apples are tender.
Serve with cream and sugar or hard sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure of the cake as its starch sets during baking.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Butter
- Adds richness and tenderness by coating flour and shortening the crumb.
- Egg
- Binds the batter and adds structure and moisture as it sets.
- Milk
- Hydrates the flour and gives the batter its moisture and softness.
- Apples
- Provide moisture and tartness, softening as they bake into the dough.

Fit is the average pairing score against flour, butter, egg, milk, apple, sugar. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
