Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Starchy base that softens when boiled and browns in the frying pan for a crisp surface.
- Butter
- Adds richness and fat, giving the sauce a smooth, rounded texture.
- Mustard
- Adds sharp, pungent flavor that cuts through the richness of the butter.
The step that matters
Fry the potatoes until golden-brown.. Browning comes from the Maillard reaction, which builds savory flavor and a crisp surface. Too little heat leaves them pale and bland, while too long dries them out.
Swap the potato
How well each one fits the dish's main ingredients (mustard, butter, pepper, vinegar):
- Horseradishfits better
- Radishfits better
- Shallotfits better
- Potatothe original
Fit is the average pairing score against mustard, butter, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
