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 ↓
Good, Cheap Layer 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 the batter
Preheat the oven to 350°F (175°C).
In a bowl, beat the egg and egg yolk with the sugar until creamy.
Add the butter and mix well.
Stir in the sweet milk.
Gradually add the flour and baking powder, mixing until smooth.
Bake the layers
Divide the batter into three layers and bake until golden.
For added flavor, mix spices and currants or raisins into the middle layer.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure and richness to the crumb as they set in the oven.
- Sugar
- Sweetens the cake and helps it brown as it bakes.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Baking powder
- Releases gas in the batter so the layers rise and become light.
- Butter
- Adds fat for tenderness and flavor in the crumb.
The step that matters
Mixing in the flour and baking powder. Overmixing once the flour is added develops gluten, which makes the layers tough and dense. Mix only until the batter is smooth, then bake promptly so the baking powder can lift the layers.
Swap the currant
The recipe marks currant as optional. How well each one fits the dish's main ingredients (egg, sugar, butter, walnut, milk, flour):
- Vanillafits better
- Raisinfits better
- Figfits better
- Currantthe original
Fit is the average pairing score against egg, sugar, butter, walnut, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
