Why it works: Butter and milk 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 ↓
Bath-buns
Ingredients
Directions
The book says “a slack oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Let the butter soften to room temperature.
In a bowl, cream the butter with a spoon.
Add the eggs one at a time, mixing well after each addition.
Gradually mix in the baking soda, sugar, flour, and milk until combined.
Shape and bake
Scoop the mixture into equal pieces the size of a nut.
Place the pieces on a baking sheet, leaving space between them.
Top each piece with a pinch of preserved cedrat.
Bake in a 300°F (150°C) oven until golden brown.
Serve
Serve the buns cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air and give the buns a tender, rich crumb.
- Eggs
- Bind the dough and add structure and richness as they set in the oven.
- Flour
- Forms the main structure of the dough as its proteins set during baking.
- Baking soda
- Reacts with the dough to produce gas, helping the buns rise and lighten.
- Sugar
- Creamed with butter for sweetness and to help browning in the oven.
- Milk
- Adds moisture to the dough and helps it come together with the flour.
The step that matters
Adding the baking soda. Baking soda needs an acid to react fully and release gas; if it is unevenly mixed, pockets of soda can leave bitter, patchy spots and uneven rising in the buns.
Swap the nutmeg
How well each one fits the dish's main ingredients (sugar, butter, flour, egg, milk):
- Cinnamonfits better
- Nutmegthe original
- Jalapenofits less well
- Capersfits less well
Fit is the average pairing score against sugar, butter, flour, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
