Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Bath Buns
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the sponge
Dissolve the yeast in ½ cup of tepid water.
Mix the dissolved yeast with the eggs and 1 lb of flour.
Beat the mixture in a bowl.
Set the mixture in a warm place to rise.
Make the dough
Rub the butter into the remaining 1 lb of flour.
Add the sugar to the butter‑flour mixture.
Mix in some sugar nibs and candied peel cut into small cubes.
Once the sponge has risen, combine all ingredients.
Cover the combined dough with a cloth.
Let the dough rise again in a warm place.
Shape and bake
Grease a baking tin.
Form the buns.
Place the buns on the tin.
Brush the buns with a mixture of egg yolk and milk.
Bake in a 400°F (200°C) oven for about 20 minutes.

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 dough's structure, which holds the buns' shape as they rise and bake.
- Eggs
- Add richness and structure, and the yolks help the buns brown.
- Compressed yeast
- Produces gas that makes the dough rise and gives the buns an airy crumb.
- Butter
- Adds fat that tenderises the crumb and gives a rich flavour.
- Sugar nibs
- Add sweetness and small pockets of crunch within the soft dough.
The step that matters
Let the sponge rise before combining. The yeast needs a warm, fully risen sponge to be active. Combining too early leaves the dough weak and slow to rise, giving dense buns.
