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 ↓
Light Bread
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the yeast
Set your yeast at room temperature by mixing 2 tablespoons of flour and 2 tablespoons of mashed potatoes.
Pour in the water from boiling the potatoes and let it cool.
Add ½ cup liquid yeast and keep in a warm place until risen.
Mix and knead
In a mixing bowl, combine the yeast mixture, a small handful of sugar, ¼ teaspoon salt, and 2 quarts of boiled and cooled water or milk.
Add flour and knead until the dough is elastic.
Cover and keep in a warm place until morning.
Shape and bake
Mold into loaves, adding just enough flour to knead, and place in pans.
When risen, bake in a moderate oven at 350°F (175°C).

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
- Flour
- Forms the gluten network that gives the dough its elastic structure and holds the loaf's shape.
- Liquid yeast
- Ferments the sugars in the dough, producing gas that makes the bread rise.
- Mashed potatoes
- Adds moisture and starch that help keep the bread soft and fresh.
- Sugar
- Feeds the yeast and adds a little sweetness and browning to the crust.
The step that matters
Knead until the dough is elastic. Kneading develops gluten, which traps the gas yeast produces. Adding too much extra flour while shaping can make the dough stiff and dense, so use only enough to handle it.
Swap the potato
How well each one fits the dish's main ingredients (flour, sugar, milk):
- Arrowrootfits better
- Sweet potatofits better
- Beetrootfits about as well
- Potatothe original
Fit is the average pairing score against flour, sugar, milk. Candidates are from the same food group and used in at least 100 recipes.
