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 ↓
A Nice Light 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
Preheat the oven to 350°F (175°C).
In a bowl, combine the flour, baking powder, and salt.
Rub the butter into the flour mixture until crumbly.
Make the batter
In another bowl, mix the milk with the beaten egg yolks.
Combine the wet and dry ingredients.
Beat the egg whites until stiff and gently fold them into the batter.
Pour the mixture into a well‑greased cake tin.
Bake
Bake for 1½ hours or until a toothpick comes out clean.

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
- Eggs
- Egg yolks bind the batter, and whipped whites add lightness and structure.
- Butter
- Rubbed into the flour, it coats flour particles and gives the cake a tender, rich texture.
- Flour
- Its proteins set during baking, forming the cake's structure.
- Baking powder
- Releases gas when heated, helping the cake rise.
- Sugar
- Adds sweetness and helps browning and a moist crumb.
- Milk
- Adds moisture and helps form a smooth, pourable batter.
The step that matters
Folding in the beaten egg whites. Stiff whites hold air that lifts the batter. Stirring them in vigorously knocks that air out, leaving a denser cake, so fold gently until just combined.
Swap the currant

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