Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Yeast Bread
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the potato starter
Peel and boil the potatoes in 2 quarts of water until done.
Pour the water over enough flour to make a stiff batter.
Mash the potatoes and let them cool.
Add a little salt and 1 teacup of yeast to the cooled potatoes.
Let the mixture stand overnight.
Make and shape the dough
Add flour to make a soft dough and let it rise.
Turn the dough out onto a kneading board and knead, adding flour until stiff enough to mold.
Let it rise again.
Bake
Butter a pan and bake the bread at 300°F (150°C) for 1 hour or until it is a rich brown color.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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 starch and moisture that give the bread a soft, moist crumb.
- Yeast
- Ferments the dough, producing gas that makes it rise.
- Flour
- Forms the gluten network that gives the dough its structure and stiffness.
The step that matters
Letting the yeast mixture stand overnight. Yeast needs time in a warm, moist mix to ferment and build flavor and leavening power. Too short a rest leaves the dough flat and dense, so the starter must be given its full standing time before the dough is made.
Swap the potato
How well each one fits the dish's main ingredients (flour, butter):
- Shallotfits better
- Leekfits better
- Arrowrootfits better
- Potatothe original
Fit is the average pairing score against flour, butter. Candidates are from the same food group and used in at least 100 recipes.
