Why it works: Flour and milk 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 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.
Prepare
Preheat the oven to 400°F (200°C).
In a bowl, mix the flour, salt, and baking powder.
In another bowl, combine the sour cream and baking soda, then beat the mixture well.
Make and shape the dough
Stir the sour cream mixture into the flour mixture.
If the dough is too dry, add a little milk.
Mix quickly and lightly until combined.
Cut out biscuits with a small cutter and place them on a baking sheet.
Bake
Bake in the preheated oven until golden brown.

Shared aroma: acetaldehyde (pungent, ethereal).
Flour and milk 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
- Flour
- Forms the main structure of the biscuits as gluten develops with mixing.
- Sour cream
- Adds moisture and fat for a tender crumb, and its acidity reacts with the baking soda.
- Baking soda
- Reacts with the sour cream's acidity to release gas, helping the biscuits rise.
- Baking powder
- Provides additional leavening so the biscuits rise in the oven.
The step that matters
Mix quickly and lightly until combined. Overmixing develops too much gluten in the flour, which makes biscuits tough instead of tender. Stop once the dry bits are just moistened.
“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.
