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

What each ingredient does

Perch
Is the main protein, cooked gently in the liquid until tender.
White wine
Adds acidity and aroma to the stewing liquid.
Catsup
Adds sweetness and tomato-based acidity, giving the gravy body and color.
Chopped onion
Adds savory depth and aroma to the stew.

The step that matters

Let it stew gently until done. Gentle heat cooks the fish through while keeping its flesh intact. Vigorous boiling can break the fish apart and toughen the flesh.

Swap the onion

How well each one fits the dish's main ingredients (pepper, white wine, lemon):

  1. Capsicumfits better
  2. Shallotfits better
  3. Spinachfits better
