Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. 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.
Prepare the batter
Preheat the oven to 350°F (175°C).
In a bowl, beat the egg and mix in the sugar until well combined.
Add the sour cream (or buttermilk) and dissolved baking soda, mixing thoroughly.
Gradually add the sifted flour and flavoring, stirring until smooth.
Bake and frost
Pour the batter into a greased cake pan.
Bake for about 25-30 minutes or until a toothpick comes out clean.
Let cool and frost with icing without eggs.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Binds the batter and adds structure as it sets in the oven.
- Sour cream or rich buttermilk
- Adds moisture and acidity that reacts with the baking soda to help the cake rise.
- Baking soda
- Reacts with the acidic sour cream or buttermilk to produce gas that lightens the crumb.
- Sifted flour
- Provides the main structure of the cake as its starches set during baking.
- Sugar
- Sweetens the cake and contributes to browning and a tender crumb.
The step that matters
Dissolve the baking soda before adding it to the batter. Baking soda must be fully dissolved and mixed through the batter so it reacts evenly with the acidic sour cream or buttermilk. Uneven mixing leaves pockets of gas-driven rise and bitter spots.
“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.
