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 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 the oven to 400°F (200°C).
In a bowl, combine the sifted flour and baking soda.
Add a little salt to the buttermilk and mix well.
If using sweet milk, add the cream tartar to the flour mixture.
Make and bake
Gradually mix the buttermilk into the flour until a dough forms.
Roll out the dough and cut into desired shapes.
Place the dough on a baking sheet and bake for about 15–20 minutes or until golden.

Flour and milk barely smell alike, yet cooks put them together in 78,219 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
- Sifted flour
- Forms the gluten network that gives the scones their structure.
- Magic soda
- Reacts with the acid in the buttermilk to release carbon dioxide, which lifts the dough.
- Sour or buttermilk
- Supplies moisture and acidity that activates the soda and tenderizes the crumb.
The step that matters
Gradually mix the buttermilk into the flour. Mixing only until the dough forms keeps it tender. Overworking develops too much gluten, which makes scones tough and dense.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
