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 ↓

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.
Make the dough
In a bowl, combine yeast, salt, and sugar.
Add 3 cups of flour to make a sponge and beat briskly for a few minutes.
Set aside to rise until light and bubbly.
Once risen, add beaten eggs, currants, and softened butter.
Knead in enough flour to form a dough and let it rise until doubled in size.
Shape and bake
Roll out the dough into a sheet and cut into rounds.
Place the rounds in a pan and let them rise until doubled in size.
Cut a cross on top of each bun with scissors.
Brush the tops with a paste made from boiling cornstarch in water.
Sprinkle with sugar and dry in the oven.
Bake at 400°F (200°C) 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 gluten structure that traps gas and gives the buns their crumb.
- Yeast
- Produces gas as it ferments, making the sponge and dough rise and turn light.
- Eggs
- Add richness and structure, helping the dough set firmly in the oven.
- Butter
- Adds fat that softens the crumb and gives a tender, rich texture.
- Sugar
- Feeds the yeast and adds sweetness and some browning to the crust.
- Currants
- Add sweet, fruity pockets of flavour throughout the buns.
The step that matters
Make the cornstarch paste with boiling water. Cornstarch must be fully cooked in boiling water to thicken into a glossy glaze; undercooked starch stays cloudy and tastes raw.
Swap the currant
How well each one fits the dish's main ingredients (sugar, flour, egg, butter):
- Raisinfits better
- Vanillafits better
- Figfits better
- Currantthe original
Fit is the average pairing score against sugar, flour, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
“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.
