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 ↓
Buttermilk Puffs
Ingredients
Directions
The book says “a very hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Combine the buttermilk and baking soda in a bowl.
Taste the mixture and add more baking soda if it is not sweet.
Stir in the salt, sugar, and enough flour to create a thick batter that drops in lumps from a spoon.
Bake
Mix quickly and drop spoonfuls onto a buttered baking pan.
Bake in a very hot oven at 400°F (200°C) for about 7 minutes, or 12 minutes if the buttermilk is not rich.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Buttermilk
- Its acidity reacts with baking soda and adds moisture and a tangy flavour.
- Baking soda
- Reacts with the buttermilk's acid to release carbon dioxide, which makes the puffs rise.
- Flour
- Provides the structure that holds the puffs together as they set in the oven.
- Sugar
- Adds sweetness and helps the puffs brown lightly.
The step that matters
Mix quickly and drop spoonfuls onto the pan. Baking soda and buttermilk start releasing carbon dioxide as soon as they meet. If the batter sits, that gas escapes before baking, so the puffs rise less. Quick mixing and a very hot oven keep the gas trapped while the structure sets.
