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
Prepare the potatoes
Boil the potatoes until tender.
Mash the potatoes with butter and enough milk to pass through a colander.
Make the dough
Mix the yeast and warm water with the potato mixture.
Combine with the flour and add salt.
Knead the dough, adding more milk or water if necessary.
Rise
Let the dough rise in a warm place until doubled in size.

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 starch and moisture, giving the bread a soft, moist crumb.
- Flour
- Forms the gluten network that gives the dough its structure.
- Yeast
- Produces gas as it ferments, making the dough rise.
- Milk
- Adds moisture and softness to the dough.
- Butter
- Adds fat, tenderising the crumb and adding richness.
The step that matters
Knead the dough, adding more milk or water if necessary. Flour absorbs liquid at different rates depending on the potatoes and flour, so the dough can be too stiff or too wet. Adjusting by small amounts gives a smooth, elastic dough that holds the gas produced by the yeast.
Swap the potato
How well each one fits the dish's main ingredients (butter, milk, flour):
- Potatothe original
- Arrowrootfits about as well
- Leekfits less well
- 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.
