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).
In a large bowl, cream together the butter and sugar.
Add the beaten eggs and sour milk, mixing well.
Stir in the baking soda and flour until combined.
Flavor the batter with spices to your taste.
Fold in the currants.
Bake
Pour the batter into a greased baking pan and bake for 30 minutes.

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.
- Sugar
- Creams with the butter and adds sweetness and browning.
- Eggs
- Bind the batter and add structure as they set in the oven.
- Sour milk
- Adds moisture and acidity that reacts with the baking soda.
- Baking soda
- Reacts with the sour milk's acidity to produce gas, helping the cake rise.
- Flour
- Forms the main structure of the cake as it sets when baked.
The step that matters
Stir in the baking soda and flour until combined.. Baking soda needs acid from the sour milk to react and lift the batter. Mixing only until combined keeps the crumb tender, since overworked flour develops gluten and makes the cake tough.
