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 gradually.
Add spices to taste and fold in the currants.
Pour the batter into a greased baking pan.
Bake
Bake for 30 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
- Butter
- Creams with sugar to trap air and add richness and tenderness to the crumb.
- Sugar
- Sweetens the cake and helps create a soft texture when creamed with butter.
- Eggs
- Bind the batter and add structure and moisture as the cake sets.
- Sour milk
- Adds moisture and acidity that reacts with the baking soda.
- Baking soda
- Reacts with the acidic sour milk to produce gas that lifts the batter.
- Flour
- Provides the structure that sets the cake as it bakes.
The step that matters
Stir in the baking soda and flour gradually. Baking soda reacts with the sour milk as soon as it is mixed in, so the batter should be mixed promptly and gently. Overmixing after the flour goes in develops gluten and can make the cake tough and dense.
Swap the currant
How well each one fits the dish's main ingredients (butter, sugar, egg, milk, flour):

Fit is the average pairing score against butter, sugar, egg, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
