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 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.
Prepare
Preheat the oven to 400°F (200°C).
Make and shape the dough
In a bowl, combine the flour, baking powder, baking soda, and salt.
Stir in the sour cream and enough sweet milk to form a dough that can be rolled out easily.
Divide the dough into two equal parts and roll each out.
Spread a small amount of butter between the layers.
Bake
Bake until golden brown.

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
- Provides the structure that holds the biscuit together as it bakes.
- Cream baking powder
- Releases gas in the dough so the biscuits rise and turn light and tender.
- 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 produce gas that helps the biscuits rise.
- Sweet milk
- Hydrates the flour so the dough forms and can be rolled out.
The step that matters
Stir in the sour cream and milk. Adding too much liquid or overmixing makes the dough tough and dense, while too little makes it dry and hard to roll. Handling the dough gently keeps the biscuits tender.
