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 large bowl, mix the flour, salt, baking soda, and sugar.
Make a well in the center and pour in the buttermilk.
Stir until a dough forms, then knead gently on a floured surface.
Shape and bake
Divide the dough into two equal pieces and shape into loaves.
Place the loaves side by side on a baking sheet, touching slightly.
Bake for 30‑35 minutes until golden brown and hollow sounding when tapped.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Forms the gluten network that gives the loaf its structure.
- Buttermilk
- Moistens the dough and its acidity reacts with the baking soda.
- Baking soda
- Reacts with the buttermilk's acid to produce carbon dioxide, lifting the loaf.
- Sugar
- Adds a little sweetness and helps the crust brown.
The step that matters
Knead gently. Overworking soda-leavened dough develops too much gluten, making the loaf tough and dense. Brief, gentle handling keeps the crumb tender while still bringing the dough together.
