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

Oven, in the book's wordsA slow oven

Ingredients

Directions

The book says “a slow oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the dough

  1. Boil the potatoes until tender, then mash them with the butter and enough milk to pass through a colander.

  2. Mix the yeast and warm water with the mashed potatoes.

  3. Combine the potato mixture with the flour and add salt.

  4. Knead the dough well, adding more warm milk or water if needed.

  5. Let the dough rise in a warm place for 1 hour.

Shape and bake

  1. Shape the dough into rolls and place them on a baking sheet.

  2. Bake in a 350°F (175°C) oven for about 30 minutes.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Potatoes
Add moisture and softness to the dough, giving the rolls a tender crumb.
Yeast
Produces gas as it ferments, making the dough rise and become light.
Flour
Forms the gluten network that gives the dough structure and chewiness.
Butter
Adds fat, which tenderizes the crumb and adds richness.

The step that matters

Kneading the dough. Kneading develops the gluten network that traps the gas from the yeast. Without enough kneading, the dough may rise poorly and the rolls can turn out dense.

Swap the potato

How well each one fits the dish's main ingredients (butter, milk, flour):

  1. Potatothe original
  2. Arrowrootfits about as well
  3. Leekfits less well
  4. Shallotfits less well

Fit is the average pairing score against butter, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
