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 ↓
Buttermilk Bread
Ingredients
Directions
The book says “a slow oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Warm the buttermilk and add the yeast and baking soda.
Stir in the sugar, salt, and butter.
Gradually add warm flour to form a soft dough.
Knead the dough well and let it rise.
Knead again, then place in greased tins.
Bake
Let it rise again and bake for about 1 hour at 350°F (175°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sour buttermilk
- Adds moisture and tang, and its acidity reacts with the baking soda to help the loaf rise.
- Yeast
- Ferments the sugars in the dough, producing gas that makes the bread rise and become airy.
- Baking soda
- Reacts with the sour buttermilk's acid to release carbon dioxide, adding lift and a tender crumb.
- Flour
- Forms the gluten network that gives the dough structure and holds the gas produced during rising.
- Butter
- Adds fat for a softer crumb and richer flavor.
The step that matters
Knead the dough well and let it rise. Kneading develops the gluten network that traps the gas from the yeast. Without enough kneading, the dough may not hold its shape or rise evenly in the tins.
“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.
