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 Scones
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 oven to 400°F (200°C).
In a large bowl, combine sifted flour and baking soda.
If using sweet milk, add cream of tartar to the flour mixture.
Make and bake
Mix in sour or buttermilk until a dough forms.
Shape dough into scones and place on a baking sheet.
Bake for 15-20 minutes or until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the scones together as they bake.
- Baking soda
- Reacts with the acid in sour milk or buttermilk to produce gas that lifts the scones.
- Sour or buttermilk
- Supplies the acid that activates the baking soda and adds moisture and tenderness.
- Cream of tartar
- Supplies acid for leavening when sweet milk is used instead of sour milk.
The step that matters
Mix in the liquid until just combined. Overworking wheat flour dough develops gluten and makes scones tough. Stirring only until a dough forms keeps them tender, and the acid-soda reaction starts as soon as liquid meets the baking soda, so the dough should go into the oven promptly.
“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.
