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 ↓

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.
Make the batter
Dissolve the saleratus in a little hot water and stir it into the buttermilk.
Gradually mix in the flour until well combined.
Beat the mixture lightly until smooth.
Bake
Pour the batter into French roll pans.
Bake at 400°F (200°C) for about 30 minutes.

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 saleratus to produce gas, lifting the dough and adding tang.
- Saleratus (baking soda)
- Reacts with the buttermilk's acid to release carbon dioxide, helping the rolls rise.
- Flour
- Forms the gluten network that gives the rolls their structure.
- Butter
- Adds fat that tenderizes the crumb and contributes richness and browning.
- Eggs
- Add structure and moisture, helping bind the batter and set during baking.
The step that matters
Dissolving the saleratus before mixing. Saleratus must be fully dissolved so it reacts evenly with the buttermilk's acid. Clumps leave pockets of bitter residue and uneven rising. Stirring it in gently keeps the gas that forms trapped in the batter.
