Why it works: Milk and butter 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 ↓
Dutch Apple Cake with Lemon Sauce
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the dough
Preheat the oven to 400°F (200°C).
Sift together the flour, salt, and baking powder.
Rub in the butter thoroughly.
Beat the egg with the milk and stir into the dry mixture.
Spread the mixture ½ inch thick on a baking pan.
Top and bake
Pare, core, and cut the apples into eight pieces each.
Stick the apple pieces into the dough in rows and sprinkle with sugar.
Bake until golden brown.
Make the sauce and serve
For the sauce, bring the cold water and sugar to a boil.
Dissolve the cornstarch in a little cold water and add it to the boiling mixture.
Remove from heat as soon as it thickens.
Stir in the butter and lemon rind and juice (or lemon extract).
Serve the cake hot with the lemon sauce.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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
- Flour
- Forms the structure of the cake base as it sets in the oven.
- Baking powder
- Releases gas during baking so the dough rises and turns light.
- Butter
- Rubbed into the flour to add richness and a tender texture.
- Egg
- Binds the dough and helps give it structure as it bakes.
- Apples
- Add moisture and fruitiness that soften and sweeten as they bake.
- Cornstarch
- Thickens the sauce as it heats, giving it a smooth, glossy body.
The step that matters
Remove the sauce from heat as soon as it thickens. Cornstarch thickens when heated but can break down and turn thin or gluey if it is overcooked, so it should come off the heat once thick.
Swap the apple
How well each one fits the dish's main ingredients (flour, egg, milk, butter, sugar, sauce, lemon):
- Vanillafits better
- Raisinfits better
- Figfits better
- Applethe original
Fit is the average pairing score against flour, egg, milk, butter, sugar, sauce, lemon. 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.
