Why it works: Milk and flour are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Sour Cream 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.
Make the dough
In a bowl, combine sour milk, sour cream, baking soda, and salt.
Gradually add flour until the mixture is soft and manageable.
Knead lightly and shape into biscuits.
Bake
Bake in a preheated oven at 400°F (200°C) until golden.

Milk and flour barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sour milk
- Its acidity reacts with baking soda to produce gas that lifts the biscuits.
- Baking soda
- Reacts with the acid in the sour milk and sour cream to make the biscuits rise.
- Sour cream
- Adds fat and acidity, giving a tender crumb and rich flavor.
- Flour
- Provides the structure that holds the biscuits together as they bake.
The step that matters
Add the flour gradually. Adding flour slowly lets you stop once the dough is soft and manageable. Too much flour makes the biscuits dense and dry, while overworking the dough by kneading too much develops gluten and toughens the texture.
“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.
