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

Oven, in the book's wordsA quick oven

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

  1. Preheat your oven to 400°F (200°C).

Make the dough

  1. In a large bowl, combine the flour, lard or butter, vinegar, and baking soda.

  2. Stir the baking soda into the vinegar until well mixed, then add to the flour mixture.

  3. Beat the eggs until light and fluffy, then incorporate them into the dough.

  4. Add warm water gradually to form a stiff dough that can be rolled out.

Shape and bake

  1. Roll out the dough to 1 inch thick and cut with a biscuit cutter.

  2. Place the biscuits on a baking sheet and 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

All-purpose flour
Forms the structure of the dough once hydrated.
Lard or butter
Adds fat that tenderises the crumb and helps browning.
Vinegar
Reacts with baking soda to produce gas that lifts the biscuits.
Baking soda
Reacts with the acid in vinegar to release carbon dioxide for rising.
Eggs
Add richness and structure, and help the biscuits set and brown.

The step that matters

Stir the baking soda into the vinegar before adding it to the flour. The baking soda and vinegar react immediately to release carbon dioxide. Mixing them first lets the reaction start evenly, so the gas is distributed through the dough for an even rise rather than pockets of soda.
