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 moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Beat together mashed potatoes, flour, eggs, lukewarm water, butter, milk, and salt in a large bowl.
Let the mixture rise for 2 hours.
Make the dough stiff, then let the dough rise for another 1½ hours.
Shape and bake
Roll the dough into sheets 1 inch thick.
Cut the dough with a biscuit cutter.
Place the cut dough into a pan.
Let the rolls rise for 1½ hours.
Bake in a moderate oven at 350°F (175°C) until golden.

Flour and butter 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
- Mashed potatoes
- Add moisture and a soft, tender crumb.
- All-purpose flour
- Provides the structure that holds the rolls together.
- Eggs
- Add structure, richness, and help bind the dough.
- Butter
- Adds fat for tenderness and a richer flavor.
- Milk
- Adds moisture and softness, and helps browning.
- Compressed yeast
- Produces gas that makes the dough rise and become light.
The step that matters
Let the dough rise fully before shaping. Yeast needs time to produce enough gas to lighten the dough. Rising too little leaves dense rolls, while rising too long can weaken the structure and make them collapse or taste sour.
Swap the potato
How well each one fits the dish's main ingredients (flour, egg, butter, milk):
- Chivefits about as well
- Potatothe original
- Leekfits about as well
- Asparagusfits about as well
Fit is the average pairing score against flour, egg, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
