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 ↓
Cream Biscuits and Doughnuts
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
Preheat the oven to 400°F (200°C).
Make the batter
In a bowl, mix the flour and cream of tartar.
In another bowl, combine the sour cream and baking soda.
Add the sweet milk to the sour cream mixture.
Combine all ingredients and mix until smooth.
Bake
Spoon the batter into greased tin cups.
Bake for 15-20 minutes 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.

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
- Sifted flour
- Provides the main structure as the batter sets in the oven.
- Cream of tartar
- Reacts with baking soda to release gas, helping the biscuits rise.
- Sour cream
- Adds acidity and moisture, tenderizing the crumb and activating the baking soda.
- Baking soda
- Reacts with the acidic sour cream to produce gas that lifts the batter.
- Sweet milk
- Adds moisture and loosens the batter to a smooth consistency.
The step that matters
Mix the batter until smooth. Mixing only until the ingredients combine keeps the crumb tender. Overmixing develops gluten, which makes biscuits tough, and the leavening gas released by the baking soda and cream of tartar escapes if the batter sits too long before baking.
“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.
