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 ↓
Hop-yeast Bread
Ingredients
Directions
Make the sponge
Make a thin sponge with yeast, warm water, and flour.
Let the sponge rise until light.
Knead into a loaf before bed.
Prepare the potato mixture
On the evening before, peel and boil potatoes.
Mash the boiled potatoes in the boiling water.
Pour the potato mixture into a breadpan with 2 tablespoons flour, 1 teaspoon salt, and 1 teaspoon sugar.
Strain the mixture.
Add a small cup of yeast to the strained mixture.
Let the mixture rise in a warm place.
Make the dough
In the morning, sift flour into the breadpan.
Make a hole in the mixture.
Pour yeast into the hole.
Add 1 quart lukewarm water with 1 teaspoon salt dissolved.
Stir until the mixture is stiff enough to knead.
Knead for 15 minutes.
Place the dough in a floured breadpan.
Cover the dough.
Let the dough rise slowly.
Shape and bake
When the dough is light, turn it onto a board.
Knead lightly into a roll.
Cut the roll into loaves.
In the morning, shape the loaf into 3 loaves.
Bake the loaves in a hot oven.
Bake the loaves for 1 hour when they are light.
Allow the loaves to cool gradually while baking.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the gluten network that gives the bread its structure and chew.
- Yeast
- Produces gas as it ferments, making the dough rise and become light.
- Potatoes
- Add starch and moisture, helping the loaves stay soft and moist.
- Sugar
- Feeds the yeast, speeding up fermentation and rising.
The step that matters
Let the dough rise slowly. Yeast needs time and warmth to ferment fully; rising too fast or too little leaves the bread dense or uneven. Letting it rise until light gives the loaves their open texture.
Swap the potato
How well each one fits the dish's main ingredients (flour, sugar):
- Arrowrootfits better
- Beetrootfits better
- Sweet potatofits better
- Potatothe original
Fit is the average pairing score against flour, sugar. Candidates are from the same food group and used in at least 100 recipes.
