Why it works: Flour and potato are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 5,355 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
The book says “a very hot oven”. The 400°F in the steps is the modern equivalent, not the book's own figure.
Make the sponge
In a large basin, make a well in the center of the flour and pour in the yeast.
Add a splash of warm water and mix into a batter.
Cover and let it stand in a warm place overnight.
Make the dough
In the morning, sprinkle salt over the flour and add enough warm water to mix into a light dough.
Cover with a cloth to prevent crusting and let it rise in a warm place until doubled in size.
Knead the dough to distribute the gas bubbles evenly until it is elastic.
Shape and bake
Shape into loaves and let rise again until doubled in size.
Bake in a very hot oven (400°F/200°C), then reduce heat and cook until the crust is a uniform brown and sounds hollow when tapped.

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.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Forms the gluten network that traps gas and gives the loaves their structure.
- Yeast
- Produces carbon dioxide gas during fermentation, which makes the dough rise.
- Salt
- Controls yeast activity and strengthens the dough's gluten structure.
- Warm water
- Hydrates the flour so gluten can form and activates the yeast.
The step that matters
Kneading until elastic. Kneading aligns gluten strands so the dough can stretch and hold gas. Under-kneaded dough rises poorly and bakes up dense.
Swap the potato
How well each one fits the dish's main ingredients (flour, hops):
- Mustardfits better
- Arrowrootfits better
- Parsnipfits better
- Potatothe original
Fit is the average pairing score against flour, hops. Candidates are from the same food group and used in at least 100 recipes.
