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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the dough
Boil the potatoes with their skins on until tender.
Drain and squeeze them in a towel to remove moisture, then peel and mash until smooth.
Mix in the butter and salt, then add the beaten egg yolks.
Stir in the milk and yeast, then gradually add flour to form a stiff dough.
Let the dough rise until doubled in size.
Shape and bake
Shape into cakes the size of an egg and let them rise again.
Bake in a preheated oven at 350°F (175°C) until light brown.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide starch and body, giving the rolls a soft, moist crumb.
- Egg yolks
- Add richness and fat, tenderizing the crumb and helping the dough hold together.
- Milk
- Hydrates the flour and adds softness and a mild sweetness to the dough.
- Yeast
- Produces gas as it ferments, causing the dough to rise and become light.
- Flour
- Forms the gluten network that gives the stiff dough structure.
- Butter
- Adds fat for tenderness and a richer flavor in the crumb.
The step that matters
Let the dough rise until doubled in size. Yeast needs enough time to produce gas and build structure; underproofed dough bakes dense, while overproofed dough can collapse and lose its rise.
