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 ↓
Salt Rising Bread
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the starter
In a bowl, combine sliced potatoes, cornmeal, sugar, and salt.
Pour boiling water over the mixture and let it stand in a warm place overnight.
Strain the liquid and add baking soda and scant salt.
Mix in enough flour to form a stiff batter and let it rise until doubled in size.
Make the dough and bake
In another bowl, combine scalded milk, boiling water, and lard to make a stiff batter.
Add the sponge (the risen mixture) and mix into loaves.
Let the loaves rise until doubled in size and bake for 45 minutes at 400°F (200°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
- Potatoes
- Provide starch and natural enzymes that feed the fermentation in the starter.
- Cornmeal
- Adds body and texture to the starter and helps it ferment.
- Flour
- Builds the structure of the batter and later the loaves.
- Scalded milk
- Adds richness, softness and browning to the crumb and crust.
- Lard
- Adds fat that tenderises the crumb and keeps it moist.
- Baking soda
- Reacts with the acidic fermented starter to lift and aerate the dough.
The step that matters
Letting the starter ferment overnight in a warm place. The starter needs a steady warm environment to ferment properly. Too cool and it stays flat; too hot and it can sour unpleasantly or spoil before the dough is mixed.
Swap the potato
How well each one fits the dish's main ingredients (sugar, flour, milk):
- Arrowrootfits better
- Sweet potatofits better
- Beetrootfits about as well
- Potatothe original
Fit is the average pairing score against sugar, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
