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 Biscuits
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.
Make the dough
Sift the flour into a bowl.
Rub in the butter or lard and salt until well combined.
Dissolve the baking soda in hot water and add it to the mixture.
Stir in the buttermilk and cold water to form a soft dough.
Shape and bake
Roll the dough into round cakes and flatten slightly with your thumb.
Bake in a preheated oven at 400°F (200°C) for 15 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.

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
- Provides the main structure that holds the risen biscuits together.
- Butter or lard
- Coats flour particles to keep the biscuits tender and creates flaky layers.
- Baking soda
- Reacts with the buttermilk's acidity to produce gas that makes the biscuits rise.
- Buttermilk
- Its acidity activates the baking soda and adds tenderness and a tangy flavour.
The step that matters
Stir in the buttermilk and cold water. Mix only until the dough just comes together. Overmixing develops gluten, which makes the biscuits tough rather than tender.
