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

What each ingredient does

White perch
Is the main protein, cooked gently in salted milk water so it stays moist and mild.
Milk
Its proteins and sugars mellow the fish's flavour and help keep the flesh tender during simmering.
Small potatoes
Boiled then fried, they give a crisp golden exterior around the fish with a soft interior.
Hard-boiled eggs
Chopped whites and yolks add texture and richness as contrasting garnish rings.

The step that matters

Bring to a near boil, then simmer until cooked. Boiling vigorously toughens fish proteins and breaks the flesh apart. Keeping the liquid just below a boil lets the fish cook gently and stay moist and intact.

Swap the parsley

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

  1. Nutmegfits better
  2. Dillfits about as well
  3. Cinnamonfits about as well
  4. Parsleythe original

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