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 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
Preheat the oven to 400°F (200°C).
Make the dough
In a bowl, mix buttermilk, baking soda, melted butter, and sugar.
Gradually add flour until a very soft dough forms.
Shape and bake
Drop spoonfuls of dough onto a baking sheet.
Bake in the preheated oven until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Buttermilk
- Provides moisture and acidity that reacts with the baking soda and tenderizes the crumb.
- Baking soda
- Reacts with the buttermilk's acid to release carbon dioxide, lifting the biscuits as they bake.
- Melted butter
- Adds fat that shortens gluten strands for a tender texture and rich flavor.
- Flour
- Forms the structure of the biscuits as its proteins hydrate and set in the oven.
- Sugar
- Adds a little sweetness and helps the surface brown during baking.
The step that matters
Gradually add flour until a very soft dough forms. Adding too much flour or mixing the dough excessively develops gluten, which makes biscuits tough and dense. Stopping once the dough just comes together keeps them light and tender.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
