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 ↓
Soda-biscuit
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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the dough
Preheat your oven to 400°F (200°C).
In a bowl, mix the sour cream and baking soda.
Gradually add flour until the dough is soft but not sticky.
Roll out the dough to a thickness of about ½ inch.
Bake and serve
Cut into desired shapes and place on a baking sheet.
Bake for 10-15 minutes or until golden brown.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- Sour cream
- Adds moisture and acidity that helps make the dough tender.
- Baking soda
- Reacts with the sour cream's acidity to produce gas that makes the biscuits rise.
- Flour
- Provides the structure that holds the biscuits together as the dough sets.
The step that matters
Gradually add flour until the dough is soft but not sticky. Too much flour makes biscuits dense and tough, while too little leaves the dough sticky and hard to shape. Adding it gradually lets you stop at the right texture.
