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 ↓

Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Mix the baking soda with the vinegar and stir well.
Make the dough
Add the flour and lard or butter to the mixture.
Beat the eggs until light and add them to the dough.
Knead until stiff enough to roll out.
Shape and bake
Cut the dough into 2-inch thick biscuits.
Bake in the preheated oven until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure that holds the biscuits together as they bake.
- Lard or butter
- Adds fat that keeps the biscuits tender and flaky.
- Baking soda
- Reacts with the acid in the vinegar to release gas that makes the biscuits rise.
- Vinegar
- Supplies the acid that activates the baking soda for lift.
- Eggs
- Add structure and richness, helping the dough bind and brown.
The step that matters
Mixing the baking soda with the vinegar. Baking soda and vinegar react as soon as they meet, releasing gas. Adding the flour promptly after mixing keeps that gas in the dough, so the biscuits rise well rather than losing their lift.
“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.
