Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Soda Muffins
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 your oven to 400°F (200°C).
Make the batter
In a bowl, cream the butter until smooth.
In a separate bowl, beat the egg yolks and whites separately, then combine them.
Add the butter to the flour and stir in the sour milk gradually.
As the butter mixes in, add the eggs and continue stirring until you have a thick, light batter.
Adjust the milk if necessary; the batter should not be too thin.
Bake
Spoon the batter into muffin tins and bake until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sour milk
- Reacts with the baking soda to produce gas that lifts the batter and adds tang.
- Baking soda
- Reacts with the acidic sour milk to release carbon dioxide, helping the muffins rise.
- Eggs
- Add structure and richness, and help the batter bind and lighten.
- Butter
- Adds fat for tenderness and flavor.
- All-purpose flour
- Provides the main structure that sets as the muffins bake.
The step that matters
Combining the sour milk with the baking soda and flour. Baking soda needs an acid to react, so the sour milk must be stirred in gradually and the batter baked promptly to keep the gas that makes the muffins rise. Overmixing can toughen the batter and knock out air.
