Why it works: Butter and flour 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 quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Mix and rise
Beat the eggs until light.
Mix the yeast, butter, lard, sugar, and flour in a bowl at noon.
Let the mixture rise.
At 4 o'clock, add a small amount of flour and work the dough again.
Shape and rise again
Place the dough into buttered pie pans and let it rise until ready for tea at 6 o'clock.
Bake
Bake in a 400°F (200°C) oven.

The flavor team
The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour 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
- Yeast or sponge
- Produces gas that makes the dough rise and become light.
- Flour
- Forms gluten that gives the bread its structure.
- Eggs
- Add structure and richness to the dough.
- Butter
- Adds fat that softens the crumb and gives flavor.
- Lard
- Adds fat that tenderizes the crumb.
- Sugar
- Feeds the yeast and adds sweetness and browning.
The step that matters
The final rise in the pans. Yeast keeps producing gas as the dough rises. If the dough is left too long before baking, the gas weakens the gluten structure, so the loaf may collapse or turn coarse. Check that it has risen before the oven is hot.
