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 ↓
Sour Cream Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Cream together the sugar and butter.
Add the well-beaten egg and re-cream the mixture.
Sift the flour, baking powder, baking soda, and salt together three times.
Add two tablespoons of the sifted dry ingredients to the creamed mixture and cream again.
Alternately add the remaining dry ingredients and sour milk to the creamed mixture.
Stir in the extract.
Beat the dough mixture vigorously for two minutes before placing it in a loaf pan.
Bake
Bake in a moderate oven at 350°F (175°C).

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the cake together as it bakes.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Baking soda
- Reacts with the acidic sour milk and sour cream to add rising and a tender crumb.
- Butter
- Creamed with sugar to trap air and add richness and tenderness.
- Sugar
- Sweetens the cake and helps create a fine, tender texture when creamed with butter.
- Sour milk
- Its acidity activates the baking soda and adds moisture and tang.
The step that matters
Beating the batter for two minutes. Vigorous beating after the flour is added develops gluten, which gives structure but can make the cake tough if overdone. Beating briefly and deliberately, then baking promptly, keeps the crumb tender while still letting the cake rise well.
“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.
