Why it works: Cream and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Potato Paste
Ingredients
Directions
Make the dough
Beat the hot mashed potatoes until light.
Add the butter, cream, and salt, and beat again.
Gradually add enough flour to make a soft dough.
Handle the dough as lightly as possible and roll it out.
Use the dough
Use the dough for meat or potato pies, or apple dumplings.

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
- Mashed potatoes
- Provide the bulk and starch that form the base of the dough.
- Cream
- Adds fat and moisture, making the dough softer and more tender.
- Butter
- Adds fat that enriches the dough and contributes to a tender texture.
- Flour
- Provides structure, binding the potato and fat into a workable dough.
The step that matters
Handle the dough as lightly as possible. Working the dough after flour is added develops gluten and gluey starch, which makes it tough. Light handling keeps the dough tender and flaky when rolled and baked.
Swap the potato
How well each one fits the dish's main ingredients (cream, butter, flour):
- Leekfits better
- Arrowrootfits about as well
- Chivefits about as well
- Potatothe original
Fit is the average pairing score against cream, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
