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 ↓
Buttermilk Biscuit
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Sift flour, baking soda, and salt into a bowl.
Preheat your oven to 400°F (200°C).
Mix the dough
Stir together melted butter and buttermilk.
Pour the buttermilk mixture into a well in the flour.
Mix quickly with minimal handling to avoid a stiff dough.
Bake
Cut out biscuits and place them in the oven to bake.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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
- All-purpose flour
- Forms the structure of the biscuits as its proteins hydrate and set during baking.
- Baking soda
- Reacts with the acidic buttermilk to produce carbon dioxide, which makes the biscuits rise.
- Sour buttermilk
- Its acidity activates the baking soda and adds moisture and tenderness to the dough.
- Melted butter
- Adds fat that shortens gluten strands, giving a tender crumb and richer flavor.
The step that matters
Mix quickly with minimal handling. Overworking the dough develops gluten, which makes biscuits tough and stiff. Handling it lightly keeps them tender and light.
