Why it works: Milk and butter 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 ↓
Sour Milk Cakes
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Grease the baking pans well.
Make and bake
In a bowl, mix the sour milk, flour, butter, sugar, salt, and baking soda until well combined.
Pour the mixture into the prepared pans.
Bake in the preheated oven until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sour milk
- Its acidity reacts with baking soda to produce gas, helping the cakes rise.
- Flour
- Provides the structure that holds the cakes together as they set.
- Baking soda
- Reacts with the acidic sour milk to release carbon dioxide for lift.
- Butter
- Adds fat for tenderness and richness in the crumb.
- Sugar
- Adds sweetness and helps the surface brown in the oven.
The step that matters
Mixing the batter. Mix only until the ingredients are combined. Overmixing develops gluten in the flour, which can make the cakes tough and dense rather than light.
“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.
