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 hot 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 flour, baking soda, butter or lard, and salt.
Add buttermilk gradually to form a soft dough.
Roll out the dough quickly and cut into biscuits.
Bake
For a variation, roll the dough thinner, spread with softened butter, dust with sugar, roll up, and cut into slices.
Place the biscuits on a buttered baking pan and bake until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the main structure of the biscuits as the dough sets in the oven.
- Baking soda
- Reacts with the acidic buttermilk to produce gas that makes the biscuits rise.
- Butter or lard
- Cut into the flour to create fat pockets that help the biscuits turn flaky and tender.
- Buttermilk
- Adds moisture and acidity that activates the baking soda and tenderizes the dough.
The step that matters
Roll out the dough quickly and cut into biscuits. Overworking or handling the dough too long warms the fat and develops gluten, making biscuits tough instead of flaky. Working briskly keeps the fat cold so it creates layers as it melts in the oven.
