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 Made with a Starter
Ingredients
Directions
Make the starter
Make a starter by soaking the yeast cake in lukewarm water, then mix in mashed potatoes, sugar, and salt.
Set the starter in a warm place overnight after adding it to the mixture, as directed below.
Make the dough
For the bread, combine mashed potatoes, sugar, and salt with boiling water when lukewarm.
Add the starter to the mixture and set it in a warm place overnight.
The next morning, reserve ½ pint of starter for the next baking.
Thicken the remaining mixture to a batter; when foamy, add lard and flour.
Knead until smooth, let it rise, then shape into loaves, allow to rise again, and bake.

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.

Egg and flour barely smell alike, yet cooks put them together in 106,462 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 cake
- Ferments the starter, producing gas that makes the dough rise.
- Mashed irish potatoes
- Adds moisture and body to the dough, giving a soft, tender crumb.
- Lard
- Adds fat that tenderises the crumb and softens the texture.
- Flour
- Forms the gluten network that gives the bread its structure.
The step that matters
Knead until smooth, then let it rise. Kneading develops gluten so the dough can trap the gas made by the yeast; under-kneaded dough rises poorly and bakes dense.
Swap the potato
How well each one fits the dish's main ingredients (sugar, egg, flour):
- Arrowrootfits better
- Sweet potatofits better
- Shallotfits better
- Potatothe original
Fit is the average pairing score against sugar, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
