Why it works: Bread and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓

Ingredients
Directions
Make the dough
Mash the cooked potatoes in a bowl.
Mix in the eggs and salt.

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.

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
- Potatoes
- Form the bulk of the dough and give the noodles a soft, tender body.
- Eggs
- Bind the mashed potato into a cohesive dough that holds its shape.
- Flour
- Adds enough structure to the dough so it can be rolled out and cut.
- Butter
- Adds richness and, when browned, a nutty aroma and color to the finished noodles.
The step that matters
Adding the flour. Too much flour makes the noodles dense and tough, while too little leaves the dough sticky and hard to roll and cut. Add it gradually until the dough just holds together.
Swap the potato
How well each one fits the dish's main ingredients (egg, flour, bread, butter):
- Shallotfits better
- Leekfits better
- Chivefits better
- Potatothe original
Fit is the average pairing score against egg, flour, bread, butter. Candidates are from the same food group and used in at least 100 recipes.
