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 ↓
Orange 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.
Make the cake
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the milk.
In a separate bowl, combine the flour, cream of tartar, and baking soda.
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Divide the batter into four layers and bake until golden brown.
Make the filling and assemble
For the filling, beat the egg white until stiff peaks form.
Gradually add the powdered sugar, orange juice, and grated rind, mixing until smooth.
Spread the filling between the layers of cake.

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.

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
- Butter
- Adds fat and richness, giving the cake a tender crumb and flavour.
- Eggs
- Provide structure and binding as the batter sets in the oven.
- Flour
- Forms the structure of the cake as its proteins set during baking.
- Cream of tartar
- Acidifies the batter, helping stabilise the egg and lift the crumb with baking soda.
- Baking soda
- Reacts with the acidic components to release gas, causing the cake to rise.
- Egg white
- Beaten to stiff peaks, it gives the filling a light, airy texture.
The step that matters
Mixing the dry ingredients into the wet mixture. Mixing only until just combined keeps the batter tender; overmixing develops gluten in the flour, which makes the cake tough and dense.
Swap the orange

Fit is the average pairing score against butter, sugar, milk, flour, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
