Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Boiled potatoes
Provide the bulk and starchy body that holds the piped border's shape.
Butter
Adds richness and a smooth, silky texture to the potato purée.
Milk
Adds moisture so the potato purée pipes smoothly.
Quinces
Soften when boiled and contribute fruity flavour and tenderness.

The step that matters

Rub the potatoes through a sieve while hot. Hot potatoes break up into a smooth, lump-free purée. As they cool, starch firms up and the potato becomes stiff and grainy, making it harder to pipe cleanly.

Swap the quince

How well each one fits the dish's main ingredients (potato, butter, milk, pepper, egg, sugar):

  1. Lemonfits better
  2. Vanillafits better
  3. Figfits better
  4. Quincethe original

Fit is the average pairing score against potato, butter, milk, pepper, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
