Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. 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.
Prepare the dough
Boil and mash the potatoes while warm with the butter, salt, and enough milk to make a soft batter.
When cool, add the flour and mix into a light dough; add more milk if necessary.
Knead the dough well, return it to the mixing pan, and let it rise until light.
Knead it again, then shape into small cakes and place them on slightly buttered baking sheets.
Let the cakes rise in a warm place until light.
Bake and finish
Bake in a preheated oven at 400°F (200°C) until done.
When finished, lightly wash the tops with water and cover with a clean towel to keep them soft.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Add moisture and a soft, tender crumb to the dough.
- Flour
- Forms the gluten structure that traps gas and gives the rolls their body.
- Yeast
- Produces carbon dioxide during rising, making the rolls light and airy.
- Butter
- Adds fat that tenderizes the crumb and gives a rich flavor.
- Milk
- Hydrates the flour and softens the dough for a tender texture.
The step that matters
Letting the cakes rise until light. Under-proofed rolls stay dense and heavy, while the yeast needs warmth and time to produce enough gas to lighten the crumb before baking.
Swap the potato
How well each one fits the dish's main ingredients (butter, flour, milk):
- Potatothe original
- Arrowrootfits about as well
- Leekfits less well
- Shallotfits less well
Fit is the average pairing score against butter, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
