Why it works: Buttermilk and flour 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 ↓
Kentucky Buttermilk Rolls
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°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 the dough
In a large bowl, combine buttermilk and baking soda. Let it sit for 5 minutes.
In another bowl, mix flour, sugar, and salt.
Melt the butter and add it to the buttermilk mixture.
Gradually add the flour mixture to the buttermilk mixture, stirring until a dough forms.
Knead the dough on a floured surface for about 5 minutes.
Rise and shape
Place the dough in a greased bowl, cover, and let it rise in a warm place until doubled in size, about 1 hour.
Punch down the dough and shape it into rolls.
Place the rolls on a baking sheet.
Bake
Preheat the oven to 350°F (175°C).
Bake for 15-20 minutes or until golden brown.

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
- Buttermilk
- Its acidity reacts with the baking soda and adds moisture and tang to the dough.
- All-purpose flour
- Its proteins form gluten, giving the dough structure so the rolls hold their shape.
- Butter
- Adds fat that tenderizes the crumb and helps the crust brown.
- Baking soda
- Reacts with the acidic buttermilk to release gas that helps the rolls rise.
- Sugar
- Adds sweetness and helps the crust brown during baking.
The step that matters
Let the dough rise until doubled. The rise lets the gluten network trap gas and grow the dough. Rolls shaped before they have doubled may bake up dense and heavy.
