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 ↓
Sour Milk Muffins
Ingredients
Directions
The book says “a hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Stir the egg into the sour milk.
Melt the butter and baking soda in the hot water.
Add the melted mixture and salt to the sour milk and mix well.
Gradually add flour until you achieve a thick batter.
Bake
Drop the batter into muffin tins, filling them half full.
Bake in a moderate oven at 350°F (175°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Binds the batter and adds structure as the muffins set.
- Sour milk
- Provides moisture and acidity that reacts with the baking soda to lift the batter.
- Baking soda
- Reacts with the acid in the sour milk to produce carbon dioxide, causing the muffins to rise.
- Butter
- Adds fat for tenderness and flavor.
- Flour
- Forms the main structure of the muffins as its proteins and starches set in the oven.
The step that matters
Gradually add flour until you achieve a thick batter.. Adding flour gradually lets you stop at a thick, scoopable consistency. Overmixing once flour is in develops gluten, which can make muffins tough and dense.
