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 ↓

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).
Beat the egg yolks with the milk in a bowl.
Beat the egg whites until stiff in another bowl.
Cream the butter and sugar together in a large mixing bowl.
Make the batter
Add the flour and baking powder to the butter mixture.
Mix in the yolk and milk mixture.
Gently fold in the beaten egg whites.
Pour the batter into a dripping pan.
Bake and serve
Bake until golden.
Once cooled, cut the cake into squares.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg whites trapped by folding add lift, and yolks add richness and structure.
- Flour
- Provides the main structure that holds the cake together as it sets.
- Butter
- Creamed with sugar to trap air and add tenderness and fat for flavour.
- Sugar
- Creamed with butter for a tender crumb and adds sweetness and browning.
- Baking powder
- Releases gas in the batter, helping the cake rise in the oven.
- Sweet milk
- Adds moisture and hydrates the flour to form the batter.
The step that matters
Gently fold in the beaten egg whites. Egg whites hold air only while whipped, so vigorous stirring deflates them and the cake rises less. Folding gently keeps the air bubbles intact for a light texture.
