Why it works: Potato and parsley are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 2,855 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

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
- Mashed potatoes
- Form the main body of the cake, giving it a soft, tender interior.
- Flour
- Dry the surface so the egg and crumbs adhere evenly.
- Beaten egg
- Acts as a glue that holds the bread crumbs to the cake.
- Bread crumbs
- Form a crisp coating that browns during frying.
- Hot fat or clarified butter
- Conducts heat to crisp and brown the outside of the cakes.
The step that matters
Frying in hot fat until golden. If the fat is not hot enough, the coating absorbs oil and turns greasy before it browns. Hot fat quickly sets the crumb crust, sealing the cake and creating the golden colour and crisp texture.
Swap the potato
How well each one fits the dish's main ingredients (flour, egg, bread, butter, parsley):
- Shallotfits better
- Chivefits better
- Leekfits better
- Potatothe original
Fit is the average pairing score against flour, egg, bread, butter, parsley. Candidates are from the same food group and used in at least 100 recipes.
