Why it works: Sugar and flour 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 ↓
Bread
Ingredients
Directions
Prepare the sponge
Cook potatoes until soft and mash to make 1 cup.
Use the potato cooking water and add enough lukewarm water to make 3 pints.
Stir in salt, sugar, and yeast, then thicken with flour.
Let the sponge rise overnight in a warm place.
Shape and bake
In the morning, add more flour to make a stiff dough.
Knead into loaves using lard on the molding board, but no flour.
Let rise. Bake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potatoes
- Add starch and moisture, giving the bread a soft, tender crumb.
- Yeast
- Produces gas during fermentation, making the dough rise and become airy.
- Flour
- Forms the gluten network that gives the dough structure and chew.
- Sugar
- Feeds the yeast and adds a little sweetness and browning in the crust.
The step that matters
Letting the sponge rise overnight. The sponge needs enough time in a warm place for the yeast to ferment and build flavour and gas before the rest of the flour is added. Too cool or too short a rise leaves the dough dense.
Swap the potato
How well each one fits the dish's main ingredients (sugar, flour):
- Arrowrootfits better
- Beetrootfits better
- Sweet potatofits better
- Potatothe original
Fit is the average pairing score against sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
