Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Potato Rolls
Ingredients
Directions
The book says “a very brisk oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the potato batter
Pare the potatoes, boil them, and mash until smooth.
Scald the milk and add it to the hot potatoes, beating until smooth.
Stir in the butter, sugar, and salt, and let the mixture cool to lukewarm.
Dissolve the yeast in 2 tablespoons of lukewarm water and stir it into the batter.
Make and rise the dough
Sift in enough flour to make a soft dough and knead for 15 minutes.
Place the dough in a greased bowl, grease the top, cover, and let rise in a warm place until doubled in size.
Work the dough down in the bowl, grease the top, and let it rise again until light.
Shape and bake
Turn the dough out onto a lightly floured board and roll it to ¾ inch thick.
Use a small round cutter to stamp out the rolls and place them in a greased baking pan.
Brush the tops with milk or melted butter and let them rise in a warm place until light.
Brush the tops again and bake in a very hot oven at 400°F (200°C) for 10 to 12 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.

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.
- Milk
- Adds moisture and softness, and its sugars help the crust brown.
- Butter
- Adds fat that tenderizes the crumb and enriches the flavor.
- Compressed yeast
- Produces gas that makes the dough rise and become light.
- Bread flour
- Its gluten forms the structure that holds the risen dough together.
- Sugar
- Feeds the yeast and adds sweetness and browning.
The step that matters
Let the dough rise until doubled. Yeast needs a warm, adequate rise to build gas and air; under-proofed rolls stay dense, while over-proofed dough can collapse in the oven.
Swap the potato
How well each one fits the dish's main ingredients (milk, butter, sugar, bread, flour):
- Sweet potatofits about as well
- Arrowrootfits about as well
- Leekfits about as well
- Potatothe original
Fit is the average pairing score against milk, butter, sugar, bread, flour. Candidates are from the same food group and used in at least 100 recipes.
