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 ↓
Potato Bread
Ingredients
Directions
The book says “a moderately hot oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Cover the potatoes with boiling water.
Cook the potatoes for 30 minutes.
Drain the potatoes and mash them.
Pour the boiling water over the mashed potatoes.
Let the mixture cool until blood-warm.
Add the yeast and 3 quarts of flour, mixing with a spoon.
Cover the bowl with a cloth and a board or tin cover.
Let the dough rise overnight (9–10 hours).
Knead and shape
In the morning, mix in the salt and half of the remaining flour.
Use the rest of the flour for kneading the dough on a board for 20–30 minutes.
Return the dough to the bowl.
Cover the dough.
Let it rise until doubled in size.
Shape the dough into loaves.
Let the loaves rise until doubled again.
Bake
Bake in a moderate oven (350°F / 175°C) for 1 hour.

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
- Starch and moisture that help the bread stay soft and moist.
- Yeast
- Produces gas as it ferments, making the dough rise and become airy.
- Flour
- Forms gluten when kneaded, giving the dough structure to hold its shape and rise.
- Sugar
- Feeds the yeast and adds a little sweetness and browning.
- Cottolene or butter
- Adds fat that tenderizes the crumb and softens the texture.
The step that matters
Let the dough rise overnight until it is fully proofed. Yeast needs enough time to ferment the dough; too little rising leaves a dense loaf, while the dough should double again after shaping so the crumb stays light.
Swap the potato
How well each one fits the dish's main ingredients (flour, sugar, butter):
- Arrowrootfits better
- Shallotfits better
- Sweet potatofits better
- Potatothe original
Fit is the average pairing score against flour, sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
