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
Make the starter
Add 1 quart of water to 1 teacup of potato yeast.
Mix in enough flour with a spoon until combined.
Let the mixture stand overnight.
Shape and bake
In the morning, add 1 pint of milk and enough flour to make a soft dough.
Let it rise until light, then knead thoroughly again and shape into loaves.
Allow it to rise again before baking in a steady oven.

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
- Potato yeast
- Provides the leavening that makes the dough rise and become light.
- Flour
- Forms the gluten structure that traps gas and holds the loaves' shape.
- Milk
- Adds richness, softness and browning to the crumb and crust.
The step that matters
Kneading the dough after the first rise. Thorough kneading develops gluten so the dough can trap gas from the yeast and hold its shape. Under-kneading leaves a dense, weak loaf that may collapse or bake unevenly.
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.
