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 says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the sponge
Mix part of the flour and yeast into a stiff batter and let it rise in a warm place.
Combine the rest of the flour with the other ingredients and mix well.
Once the batter is light, form it into dough and let it rise for 1 hour.
Shape and bake
Shape the dough into 2 or 3 round loaves and place them on a baking sheet to rise for another 30 minutes.
Before baking, beat the yolk of an egg and glaze the loaves with it.
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
- Fine flour
- Provides the structure that holds the loaves together as they rise and bake.
- German yeast
- Produces gas that makes the stiff batter and dough rise and turn light.
- Fresh butter
- Adds fat that softens the crumb and gives a rich, tender texture.
- Sugar
- Sweetens the bread and helps the crust brown during baking.
- Eggs
- Add richness and moisture, and the yolk glaze helps the crust brown.
- Currants or sultanas
- Add sweetness and chewy pockets of fruit throughout the loaf.
The step that matters
Letting the batter become light before shaping. Yeast needs time and warmth to produce enough gas. Shaping too early leaves a dense loaf, while the dough should be visibly light before the second rise.
Swap the currant

Fit is the average pairing score against flour, butter, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
