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 ↓
Vinegar 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).
Beat the butter until creamy, then add the sugar and mix well.
Add the eggs one at a time, beating well after each addition.
In a separate bowl, mix the milk, baking soda, and vinegar.
Pour the milk mixture into the butter mixture and stir thoroughly.
Gradually add the flour, then mix in the sultanas or peel.
Bake
Butter a baking tin well and pour in the batter.
Bake for 1 hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with the sugar to trap air and give the cake a tender, rich crumb.
- Eggs
- Add structure and richness, binding the batter as it sets in the oven.
- Flour
- Forms the cake's main structure as its proteins set during baking.
- Baking soda
- Reacts with the vinegar to release carbon dioxide, helping the cake rise.
- Vinegar
- Acidifies the milk and reacts with baking soda to produce lift and a light crumb.
- Sugar
- Sweetens the cake and helps tenderize the crumb while creaming with the butter.
The step that matters
Adding the milk and vinegar mixture to the batter. The baking soda and vinegar react as soon as they are combined, releasing gas. Stirring the mixture in promptly, and not letting it sit, keeps that lift in the batter for the oven to set.
