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 the lard, riced potatoes, sugar, and salt.
Add the beaten eggs.
Add the milk.
Add 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.
Butter the top.
Let rise again.
Bake in a preheated oven at 400°F (200°C) until golden.

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 structure and chew.
- Riced potatoes
- Add moisture and a soft, tender crumb to the dough.
- Lard
- Adds fat that tenderizes the crumb and keeps the rolls soft.
- Eggs
- Add richness and structure, helping the dough hold together and brown.
- Sugar
- Feeds the yeast and adds sweetness and browning in the baked crust.
- Yeast
- Produces carbon dioxide during rising, leavening the dough and giving it lightness.
The step that matters
Let rise again. The dough must rise fully before baking so the yeast's gas is trapped in the gluten network. Underproofed rolls stay dense, while overproofed dough can collapse in the oven.
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.
