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 Pupfs
Ingredients
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, combine the buttermilk and baking soda; taste and add more baking soda if not sweet.
Stir in the salt, sugar, and enough flour to create a thick batter that drops in lumps from a spoon.
Mix quickly and drop spoonfuls onto a buttered baking pan.
Bake
Bake in a very hot oven at 400°F (200°C) for about 7 minutes.
If the buttermilk is not rich, rub a little butter into the flour until it resembles sand.
Total baking time should be about 12 minutes.

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 the baking soda and adds tang and tenderness.
- Baking soda
- Reacts with the acid in the buttermilk to release gas that makes the pups rise.
- Flour
- Provides the structure that sets in the oven and holds the pups together.
The step that matters
Mix quickly and drop the batter right away. Baking soda starts reacting with the buttermilk's acid as soon as they meet, so gas escapes if the batter waits. Overmixing also develops gluten, which makes the pups tough.
