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 very 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).
Stir the baking soda into the buttermilk.
Make and shape the dough
Make a well in the center of the flour and pour in the buttermilk mixture.
Add the salt and soft lard, then mix with your fingers to form a soft dough.
Roll out the dough to 1 inch thick and cut into biscuits.
Place the biscuits on a baking sheet, leaving space between them.
Bake
Bake in the preheated oven until golden brown.

What each ingredient does
- Buttermilk
- Its acidity reacts with the baking soda to create lift and a tender crumb.
- Baking soda
- Reacts with the acidic buttermilk to release carbon dioxide, helping the biscuits rise.
- Soft lard
- Fat coats the flour and shortens gluten strands, giving a tender, flaky texture.
- Flour
- Forms the structure of the biscuits once it hydrates into dough.
The step that matters
Mixing the dough. Mixing only until the dough just comes together keeps gluten development limited, so the biscuits stay tender rather than tough. Overworking also warms the fat, reducing flaky layers.
