Why it works: Potato and milk 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 ↓

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.
Make the potato starter
Cook the potatoes until very soft, then mash until creamy.
Pour scalding hot water over the mashed potatoes and stir in flour until the mixture resembles cake batter.
Once cool, stir in the yeast dissolved in a little warm water and let rise overnight.
Make the dough
In the morning, heat the milk until warm and add it to the yeast mixture.
Stir in flour to create a thick sponge and let it rise.
Work the mixture into a stiff dough and let it rise again.
Knead the dough down and let it rise once more.
Shape and bake
Shape the dough into loaves and let them rise until light.
Bake in a preheated oven at 350°F (175°C) for 45 minutes to 1 hour.
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.

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.

Flour and milk 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
- Potatoes
- Provide starch and moisture that give the bread a soft, tender crumb.
- Flour
- Forms the gluten network that gives the dough structure and holds the rise.
- Yeast
- Ferments sugars in the dough, producing gas that makes the bread rise.
- Milk
- Adds moisture, softness, and some sugars that help browning in the crust.
The step that matters
Let the starter rise overnight after adding the yeast. The yeast needs time to ferment the starch and sugars in the potato mixture. Rising too briefly leaves the dough dense, while the long rise builds flavour and gas for a light loaf.
Swap the potato
How well each one fits the dish's main ingredients (flour, milk):
- Arrowrootfits better
- Potatothe original
- Sweet potatofits about as well
- Parsnipfits about as well
Fit is the average pairing score against flour, milk. Candidates are from the same food group and used in at least 100 recipes.
