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 says “a hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the sponge
In a large bowl, create a sponge by mixing 1 cup of warm water, 1 cup of milk, and 1 cup of yeast in the center of 4 cups of flour.
Beat the sponge with a wooden spoon for 15 minutes and let it rise overnight in a warm place.
Knead and shape
In the morning, mix and knead the dough for 30 minutes, adding flour to form a stiff dough.
Shape the dough into small loaves and place them in pans to rise again in a warm area until light.
Bake
Bake in a preheated oven at 350°F (175°C) until golden brown.

The flavor team
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
- All-purpose flour
- Forms the gluten network that gives the bread its structure and chew.
- Yeast
- Ferments the sugars in the flour, producing gas that makes the dough rise.
- Milk
- Adds richness and softness to the crumb and helps browning.
- Potatoes
- Optional addition that can add moisture and a softer texture to the crumb.
The step that matters
Kneading the dough to a stiff texture. Kneading develops the gluten network that traps gas from the yeast. Adding flour until the dough is stiff controls stickiness, so the loaves hold their shape and rise well.
Swap the potato
The recipe marks potato as optional. 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.
