Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Layer Cake
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Cream the butter in a bowl.
Add lemon juice and egg yolks, then beat until smooth.
Fold in the egg whites, one quarter at a time.
Mix in the milk and rose water.
Sift together flour, cornstarch, and baking powder, then add to the mixture.
Bake and ice
Pour into a jelly cake pan and bake at 400°F (200°C) until light brown.
For the icing, boil powdered sugar and water until cool, then add egg whites and vanilla sugar.
Layer the cake with icing and sprinkle grated coconut between layers and on top.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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
- Creamed with sugar-free base to add richness and a tender crumb.
- Egg yolks
- Add richness, fat and colour to the batter.
- Egg whites
- Folded in to lighten the batter and help it rise and set structure.
- Flour
- Forms the main structure of the cake as it sets in the oven.
- Cornstarch
- Softens the crumb, giving a more tender texture than flour alone.
- Baking powder
- Releases gas in the batter so the cake rises in the oven.
The step that matters
Folding in the egg whites. Folding gently keeps the air beaten into the whites. Stirring hard knocks that air out, so the cake rises less and turns dense.
Swap the lemon

Fit is the average pairing score against butter, egg, milk, rose, flour, sugar, vanilla. Candidates are from the same food group and used in at least 100 recipes.
