Why it works: Cream and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Sour-cream Biscuit
Ingredients
Directions
The book says “a 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).
Sift together the flour, salt, and baking soda.
Grease a pan with butter or flour.
Make and bake the biscuits
Quickly mix the buttermilk and sour cream into the flour mixture.
Shape the biscuits quickly and bake them immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the structure that holds the biscuits together as they bake.
- Baking soda
- Reacts with the acidic buttermilk and sour cream to produce gas that lifts the biscuits.
- Buttermilk
- Adds acidity that activates the baking soda and contributes moisture and tenderness.
- Sour cream
- Adds fat and moisture, making the biscuits richer and more tender.
The step that matters
Quickly mix the buttermilk and sour cream into the flour mixture. Once the liquid meets the baking soda, gas starts forming right away. Overmixing develops gluten and knocks out bubbles, so a tough, flat biscuit results. Mix only until just combined.
