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 ↓
Jelly Cake- Apple
Ingredients
Directions
Make the batter
Cream the butter and sugar together.
Add the eggs, flour, ammonia, and milk.
Mix to a rather thin batter.
Bake in greased jelly cake tins.
Make the apple filling
Peel and slice the apples, then cook them with 1½ lb sugar until tender.
Remove from heat, rub the apples through a fine sieve, and mix in a little butter.
Assemble and finish
Once cooled, spread the apple mixture between the layers of the cake.
Sprinkle the top with sifted sugar.

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
- Flour
- Forms the cake's structure as the batter sets in the tins.
- Eggs
- Add structure and richness, helping the batter bind and rise.
- Butter
- Adds fat for a tender crumb and rich flavour.
- Sugar
- Sweetens the cake and helps create a tender texture when creamed with butter.
- Ammonia
- Acts as a leavening agent, releasing gas as the cake bakes so it lightens.
- Apples
- Provide moisture, sweetness and tartness to the filling that sits between the layers.
The step that matters
Spread the filling only once the apples have cooled. Spreading warm apple mixture onto the cake layers can soften and soak into the crumb, making the layers slide or turn soggy and hard to stack evenly.
Swap the apple
How well each one fits the dish's main ingredients (butter, flour, sugar, egg, milk):
- Vanillafits better
- Raisinfits better
- Figfits better
- Applethe original
Fit is the average pairing score against butter, flour, sugar, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
