Why it works: Cream and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓

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).
Dust the baking pans with flour.
Make the dough
In a bowl, mix the flour, salt, baking soda, and cream of tartar thoroughly.
Add buttermilk gradually to form a dough.
Optionally, add a little butter to the dough for flavor.
Bake
Shape the dough and place it in the pans.
Bake immediately 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 butter barely smell alike, yet cooks put them together in 124,287 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 dough once hydrated.
- Baking soda
- Reacts with acid to release carbon dioxide, which makes the bread rise.
- Cream of tartar
- Supplies acid that reacts with baking soda to create lift and a tender crumb.
- Buttermilk
- Hydrates the flour and its acidity helps the leavening react.
- Butter
- Adds fat for richer flavor and a softer crumb.
The step that matters
Bake immediately after shaping. Baking soda and acid begin reacting as soon as the dough is wet. Delaying the bake lets much of the carbon dioxide escape, which reduces rise and leaves a denser loaf.
