Why it works: Flour and sugar are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. The science ↓
Potato Bread
Ingredients
Directions
Prepare the potatoes
Boil 12 medium-sized potatoes until very soft.
Drain the boiled potatoes and peel them.
Mash the peeled potatoes while hot, ensuring no lumps remain.
Measure out 3 pounds (about 5 solidly packed half-pint cupfuls) of the mashed potatoes and let them cool to lukewarm.
Make the sponge
Mix the yeast with 3 tablespoons of lukewarm water until smooth.
Add the yeast mixture to the mashed potatoes.
Rinse the cup used for the yeast with 1 tablespoon of water and add it to the potato mixture.
Stir in the salt, sugar, and about 4 ounces of flour (1 scant half pint).
Mix thoroughly by hand without adding more water.
Let the mixture rise until very light, about 2 hours at 86°F (30°C).
Make and bake the dough
Add the remaining flour.
Knead until a smooth, elastic dough forms.
Add water only if necessary to achieve desired consistency.
Allow the dough to rise until it has tripled in volume, about 1 to 2 hours.
Divide the dough into four parts.
Shape each part into a loaf.
Place the loaves in greased, slightly warmed pans.
Let the loaves rise until doubled in volume.
Bake for 45 minutes at 400°F (200°C).

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.

Bread and flour barely smell alike, yet cooks put them together in 10,383 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
- Potatoes
- Provide moisture and starch that give the bread a soft, tender crumb.
- Bread flour
- Forms gluten network that gives the dough structure and elasticity.
- Yeast
- Ferments sugars to produce carbon dioxide, causing the dough to rise.
- Sugar
- Feeds the yeast and adds a little sweetness and browning.
The step that matters
Let the mixture rise until very light. Yeast needs enough time to ferment the sponge and build gas and flavor. Underproofed dough bakes dense, while overproofed dough collapses and loses structure.
Swap the potato
How well each one fits the dish's main ingredients (bread, flour, sugar):
- Arrowrootfits better
- Shallotfits better
- Sweet potatofits better
- Potatothe original
Fit is the average pairing score against bread, flour, sugar. Candidates are from the same food group and used in at least 100 recipes.
