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 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Warm the buttermilk.
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.
Let it rise until doubled in size.
Shape and bake
Knead again and place in greased tins.
Let it rise again.
Bake at 400°F (200°C) for about 1 hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sour buttermilk
- Its acidity reacts with baking soda to produce gas, helping the bread rise and adding tang.
- Yeast
- Ferments sugars and produces gas that makes the dough rise and become light.
- Baking soda
- Reacts with the acid in sour buttermilk to release carbon dioxide for extra lift.
- Flour
- Forms gluten when kneaded, giving the dough structure to trap gas and hold its shape.
- Butter
- Adds fat that tenderizes the crumb and enriches flavor.
The step that matters
Let it rise until doubled in size. Yeast needs time to produce enough gas to expand the gluten network. Underproofed dough bakes dense, while overproofed dough may collapse and lose structure.
