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 cool oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Break 1 egg into a cup and fill the cup with sour cream.
Pour the mixture into a mixing bowl and add 1 cup of sugar; mix well.
Sift together 1½ cups of flour, ¼ teaspoon of baking soda, and ¼ teaspoon of salt; add to the bowl.
In a separate bowl, combine ¼ cup of melted butter, 2 eggs, and ¼ cup of milk; mix well.
Pour the liquid mixture into the dry ingredients and mix for 2 minutes.
Bake
Spread the batter thicker around the edges of the pan.
Bake in a cool oven at 300°F (150°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide structure and richness as the batter sets in the oven.
- Sour cream
- Adds moisture and tenderness, and a mild tang to the crumb.
- All-purpose flour
- Forms the main structure of the cake as the proteins set.
- Baking soda
- Reacts with the acidity of the sour cream to help the cake rise.
- Sugar
- Sweetens the cake and helps tenderize the crumb and brown the crust.
- Melted butter
- Adds fat for richness and a moist, tender texture.
The step that matters
Spread the batter thicker around the edges of the pan. Batter tends to rise higher in the center, so a thicker rim helps the cake bake more evenly and level out instead of domed or underdone at the edges.
“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.
