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 ↓
Potato Rolls
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 dough
Dissolve the yeast in lukewarm water.
In a bowl, mix lard, mashed potatoes, sugar, and salt.
Add the beaten eggs and milk to the mixture.
Stir in the dissolved yeast.
Gradually add about 4 cups of flour to form a soft dough.
Cover and let rise for 2 hours.
Shape and bake
Shape the dough into rolls or a loaf and place on a baking sheet.
Cover and let rise again.
Preheat the oven to 400°F (200°C) and bake until golden brown.

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 dough its structure and chew.
- Mashed potatoes
- Adds moisture and starch, keeping the rolls soft and tender.
- Lard
- Adds fat that tenderizes the crumb and softens the texture.
- Eggs
- Add structure and richness, helping the rolls hold together and brown.
- Yeast
- Produces gas during rising, leavening the dough so it becomes light.
- Sugar
- Feeds the yeast and adds sweetness and golden browning in the oven.
The step that matters
Gradually add the flour to form a soft dough. Adding too much flour at once or too quickly makes the dough stiff and dense. A soft, slightly sticky dough gives a moister, lighter roll once the gluten has developed and the yeast has risen.
Swap the potato
How well each one fits the dish's main ingredients (flour, milk, egg, sugar):
- Arrowrootfits better
- Sweet potatofits better
- Asparagusfits about as well
- Potatothe original
Fit is the average pairing score against flour, milk, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
