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 ↓

Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the dough
Peel and boil the potato until tender, then mash it finely and let it cool slightly.
While the potato is still warm, stir in the butter until melted.
Sift the salt and sugar into the flour, then rub in the lard.
Add the yeast and gradually mix in the warm milk, kneading for 15 to 20 minutes.
Cover the dough and let it rise overnight.
Shape and bake
In the morning, shape the dough into rolls, about 3 to 4 inches long, using minimal flour.
Place the rolls in two rows in a buttered pan, keeping them close together.
Let the rolls rise for as long as possible before baking, ideally for 2 hours if baking at lunchtime.
Bake in a preheated oven at 350°F (175°C) until golden brown.

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
- Potato
- Adds moisture and starch that keep the rolls soft and tender.
- All-purpose flour
- Forms the gluten network that gives the dough its structure.
- Active dry yeast
- Produces carbon dioxide during the long rise, leavening the rolls.
- Butter
- Adds fat that tenderizes the crumb and richness to the flavor.
- Warm milk
- Hydrates the flour and feeds the yeast while adding softness and flavor.
- Sugar
- Feeds the yeast and adds sweetness and browning in the crust.
The step that matters
Kneading and the overnight rise. Kneading develops gluten so the dough can trap gas. Letting it rise fully before baking gives the yeast time to build a light, airy texture, so under-proofed rolls will bake up dense.
Swap the potato
How well each one fits the dish's main ingredients (butter, sugar, flour, milk):
- Arrowrootfits about as well
- Sweet potatofits about as well
- Potatothe original
- Leekfits about as well
Fit is the average pairing score against butter, sugar, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
