Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Vinegar Biscuits
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.
Prepare
Preheat the oven to 400°F (200°C).
Make the dough
In a bowl, mix the baking soda with the vinegar and stir well.
Add the flour and lard or butter to the mixture.
Beat the eggs until light and add them to the dough.
Knead until the dough is stiff enough to roll out.
Shape and bake
Roll out the dough to 2 inches thick and cut with a biscuit cutter.
Bake in the preheated oven until golden.

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
- Flour
- Forms the structure of the biscuits once kneaded and rolled.
- Lard or butter
- Adds fat that keeps the biscuits tender and flaky.
- Vinegar
- Reacts with the baking soda to produce gas that helps the biscuits rise.
- Baking soda
- Reacts with the vinegar to lift the dough as it bakes.
- Eggs
- Add richness and moisture and help bind the dough.
The step that matters
Mixing the baking soda with the vinegar. The soda and vinegar react right away, releasing gas. The dough should be handled and baked soon after so the gas still lifts the biscuits rather than escaping.
“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.
