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 ↓
Apple Jelly 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the cake
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the sweet milk, flour, eggs, and baking powder; mix until smooth.
Pour the batter into a greased cake pan and bake for 25-30 minutes.
Make the apple jelly
For the jelly, combine the grated apple, lemon juice, lemon rind, sugar, and egg in a bowl. Mix thoroughly and cook over hot water until thickened.
Let the jelly cool, then spread it between the cake layers.
Finish
Dust the top of the cake with sugar before serving.

Butter and flour 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
- Butter
- Creams with the sugar to trap air, giving the cake a tender, fine crumb.
- Flour
- Forms the structure of the cake as the batter sets in the oven.
- Eggs
- Bind the batter and help set the cake structure; the egg also thickens the jelly.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Grated tart apple
- Provides moisture, tart flavor, and body for the jelly filling.
- Lemon juice and rind
- Adds acidity and aroma that brighten the sweet apple jelly.
The step that matters
Cooking the jelly over hot water until thickened. The egg and grated apple thicken as they gently heat; cooking too hard can curdle the egg and make the jelly grainy, while stopping too early leaves it too thin to spread between the layers.
Swap the apple
How well each one fits the dish's main ingredients (butter, sugar, milk, flour, egg, lemon):
- Vanillafits better
- Raisinfits better
- Figfits better
- Applethe original
Fit is the average pairing score against butter, sugar, milk, flour, egg, lemon. Candidates are from the same food group and used in at least 100 recipes.
