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 sharp oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Make a sponge with the yeast, mixing it with a little tepid water and flour; let it sit for 15 minutes.
Combine the sponge with flour and butter; mix lightly.
Add the egg yolks and a little milk; mix until smooth.
Shape and bake
Once proved, work in the broken loaf sugar.
Shape the mixture into rock‑like forms on a buttered baking sheet.
Top each bun with a few comfits and bake in a preheated oven at 400°F (200°C) until golden.

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
- German yeast
- Raises the dough by fermenting, giving the buns a light, airy crumb.
- All-purpose flour
- Provides the structure that holds the buns together as they rise and bake.
- Unsalted butter
- Adds fat for a tender texture and rich flavour.
- Egg yolks
- Add richness, colour and tenderness through fat and emulsifying proteins.
- Loaf sugar
- Adds sweetness and crunchy pockets that caramelise on the surface while baking.
The step that matters
Working in the broken loaf sugar after proving. Sugar added to a risen dough can deflate it if handled roughly, so mix gently to keep the gas bubbles that give the buns their lightness.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
