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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat your oven to 350°F (175°C).
Make the batter
In a bowl, cream together the sugar and butter until light and fluffy.
Add the sour milk and beaten eggs, mixing well.
Sift together the baking soda and spices, then fold into the mixture.
Bake
Pour the batter into a greased cake pan and bake for 30-35 minutes or until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Sweetens the cake and, creamed with butter, helps give it a light, tender crumb.
- Butter
- Adds fat for richness and, creamed with sugar, traps air that helps the cake rise and stay soft.
- Sour milk
- Adds moisture and acidity that reacts with the baking soda to help the cake rise.
- Eggs
- Add structure and binding, helping the batter hold together as it bakes.
- Baking soda
- Reacts with the acidic sour milk to release gas, making the cake rise.
- Mixed spices
- Provide aroma and flavour to the cake.
The step that matters
Folding in the baking soda and spices. Baking soda needs acid from the sour milk to release gas, so it should be evenly distributed through the batter. Folding gently keeps the air in the batter, so the cake rises well and stays tender rather than dense.
