Why it works: Buttermilk and flour are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 3,721 recipes. Both carry ethanol, which smells alcoholic, ethereal. 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 the batter
Preheat oven to 350°F (175°C).
Beat the egg and add salt, sugar, sour cream, and buttermilk.
Stir in the baking soda.
Gradually add Graham flour until you achieve a medium batter consistency.
Bake
Pour the batter into a greased baking dish and bake until golden.

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.
- Baking soda
- Reacts with the acidic sour cream and buttermilk to produce gas that lifts the batter.
- Sour cream
- Adds acidity and moisture, tenderising the crumb and activating the baking soda.
- Buttermilk
- Adds acidity and moisture, tenderising the crumb and activating the baking soda.
- Graham flour
- Forms the main structure of the cake and sets as the batter bakes.
The step that matters
Stir in the baking soda promptly and bake soon after. Baking soda reacts with the acid in the sour cream and buttermilk right away, releasing gas. If the batter waits too long before going into the oven, much of that lift is lost, leaving a denser cake.
