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 ↓

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 large bowl, combine the flour, salt, baking soda, baking powder, and lard. Mix thoroughly.
Add the buttermilk and stir until a soft dough forms.
Shape and bake
Pat the dough on a floured surface and cut into rounds.
Place the rounds on a baking sheet and bake for about 20 minutes.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- Flour
- Forms the structure of the biscuit as its proteins and starch set in the oven.
- Baking soda
- Reacts with the buttermilk's acidity to produce carbon dioxide, helping the biscuits rise.
- Baking powder
- Provides additional leavening gas so the biscuits rise further during baking.
- Lard
- Coats flour particles and creates tenderness and flakiness by limiting gluten development.
- Buttermilk
- Hydrates the flour to form a soft dough and its acidity activates the baking soda.
The step that matters
Mix the dough only until it comes together. Stirring buttermilk into the flour too much develops gluten, making the biscuits tough rather than tender. Mixing just until a soft dough forms keeps them light.
