Why it works: Potato and mustard are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 1,340 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potatoes
- Forms the main body of the ball, giving it bulk and a soft, fluffy interior.
- Egg yolk
- Binds the potato mixture so it holds its shape when rolled and chilled.
- Flour
- Absorbs surface moisture and helps the mixture stay firm enough to shape.
- Minced ham
- Provides savory flavor and richness at the center of each ball.
- Beaten egg
- Acts as a glue so the cracker crumbs adhere evenly to the outside.
- Cracker crumbs
- Form a crisp outer coating that browns during frying.
The step that matters
Chill until stiff before frying. Cold chilling firms the starch and fat in the potato and egg coating so the balls hold their shape and crumb coat does not slide off in hot oil.
Swap the potato
How well each one fits the dish's main ingredients (pepper, flour, egg, ham, mustard):
- Shallotfits better
- Horseradishfits better
- Lettucefits better
- Potatothe original
Fit is the average pairing score against pepper, flour, egg, ham, mustard. Candidates are from the same food group and used in at least 100 recipes.
