Why it works: Flour and cream 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 ↓
Sour Cream Biscuits
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.
Make the dough
Dissolve the baking soda in a little warm water and add it to the sour cream.
Sift the salt and cream of tartar through the flour.
Mix quickly, working just enough to combine the ingredients.
Shape and bake
Roll out the dough, cut with a small cutter, and bake in a 400°F (200°C) oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Gluten forms the structure that holds the risen biscuit together.
- Sour cream
- Adds moisture and fat for tenderness, and its acidity activates the baking soda.
- Baking soda
- Reacts with the sour cream's acid to release carbon dioxide for rising.
- Cream of tartar
- Adds extra acid that works with the baking soda to lift the dough.
The step that matters
Mix quickly, just enough to combine. Overmixing develops too much gluten in the flour, making biscuits tough and dense. Brief mixing keeps them tender and lets the leavening work while the dough is still airy.
