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 ↓
Soda Biscuit
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat your oven to 400°F (200°C).
Make the dough
In a large bowl, combine the flour, baking soda, and baking powder.
Cut in the butter or lard until the mixture resembles coarse crumbs.
Stir in the buttermilk until the dough is smooth.
Bake
Drop spoonfuls of dough onto a baking sheet.
Bake for 10-15 minutes or until golden brown.

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 egg barely smell alike, yet cooks put them together in 106,462 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
- Forms the main structure of the biscuit as its proteins hydrate into gluten.
- Baking soda
- Reacts with the acidic buttermilk to produce carbon dioxide, helping the biscuits rise.
- Baking powder
- Adds additional leavening so the biscuits rise further in the oven.
- Butter or lard
- Cut into the flour to create pockets that separate layers and add tenderness.
- Buttermilk
- Its acidity activates the baking soda and its liquid hydrates the flour.
The step that matters
Cutting in the butter or lard. Fat left in pieces coats flour particles and creates layers when it melts in the oven. Overworking the dough once liquid is added develops gluten, which can make biscuits tough.
