Why it works: Milk and potato are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 3,611 recipes. Both carry (e,z)-2,6-nonadienal, which smells cucumber, melon. The science ↓
Potato Yeast Bread
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the dough
Combine milk and water in a bowl.
Mash the boiled potatoes and add to the mixture.
Stir in sugar, flour, fat, yeast, salt, and warm water.
Knead the dough until smooth.
Let it rise in a warm place until doubled in size.
Shape and bake
Shape the dough into loaves and place in greased pans.
Allow to rise again until puffy.
Bake in a preheated oven at 350°F (175°C) for 30-40 minutes.
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.

Milk and flour barely smell alike, yet cooks put them together in 78,219 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
- Flour
- Forms the gluten network that gives the loaves their structure and chew.
- Yeast
- Ferments the sugars in the dough, producing gas that makes the bread rise.
- Boiled potatoes
- Add moisture and starch, keeping the crumb soft and helping the loaf stay fresh.
- Sugar
- Feeds the yeast and adds sweetness and browning in the crust.
- Fat
- Tenderises the crumb and adds richness to the soft texture.
The step that matters
Let it rise until doubled in size. The first rise must be long enough for the yeast to build enough gas and gluten to stretch. Underproofed dough bakes dense, while overproofed dough collapses and loses structure.
Swap the potato
How well each one fits the dish's main ingredients (milk, sugar, flour):
- Arrowrootfits better
- Sweet potatofits better
- Beetrootfits about as well
- Potatothe original
Fit is the average pairing score against milk, sugar, 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.
