Why it works: Flour and buttermilk 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 ↓

Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
In a bowl, mix the baking soda into the buttermilk.
Add the egg and stir to combine.
Gradually add the flour, stirring slowly until the batter is smooth.
Bake
Pour the batter into a greased baking dish.
Bake in a hot oven at 400°F (200°C) until golden.

The flavor team
The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Shared aroma: 1-octen-3-ol (mushroom, earthy).
Flour and egg barely smell alike, yet cooks put them together in 106,462 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
- Unbolted flour
- Provides the structure that sets the batter into a crumb as it bakes.
- Buttermilk
- Adds moisture and acidity that react with the baking soda to lift the batter.
- Egg
- Binds the batter and adds structure and richness to the crumb.
- Baking soda
- Reacts with the acidic buttermilk to produce gas that makes the bread rise.
The step that matters
Stirring the flour in gradually and slowly. Once the flour is added, gluten begins to form, and overmixing makes the bread tough and dense. Stirring slowly until the batter is just smooth keeps the crumb tender. Baking soda starts reacting with the buttermilk right away, so the batter should go into the oven promptly.
