Why it works: Cream and flour are a kitchen classic. They rank in the top 20% of all ingredient pairs, and cooks put them together in 30,481 recipes. Both carry acetaldehyde, which smells pungent, ethereal. The science ↓

Ingredients
Directions
The book says “a moderately hot 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).
Make and shape the dough
In a bowl, combine sour cream and baking soda.
Gradually add flour until the mixture is soft but manageable.
Roll out the dough and cut into thin pieces.
Bake
Bake quickly until golden brown.

What each ingredient does
- Sour cream
- Adds moisture and acidity, giving the biscuit a tender crumb and rich flavor.
- Baking soda
- Reacts with the sour cream's acidity to produce carbon dioxide, helping the biscuits rise.
- Flour
- Provides structure as it hydrates, forming the dough that holds the biscuit's shape.
The step that matters
Gradually add flour until soft but manageable. Adding flour gradually lets you stop at the right consistency. Too much flour makes the dough dense and tough, while too little leaves it sticky and hard to shape.
