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

What each ingredient does

Cream
Moistens the flaked fish, keeping it tender and binding the layers softly.
Mashed potatoes
Forms the soft, moist layers that hold the fish and eggs together in the mold.
Hard-boiled eggs
Add firm texture and mild richness between the layers of fish and potato.
Butter
Greases the mold so the chartreuse releases cleanly and adds richness to the surface.

The step that matters

Steam for 20 to 30 minutes, depending on the size of the mold. Steam heats the mold gently and evenly. Too little time leaves the centre cold and loose, while overcooking dries the fish and potato and makes the layers crumbly. Matching the time to the mold size keeps the set even.

Swap the potato

How well each one fits the dish's main ingredients (fish, cream, pepper, egg, butter):

  2. Asparagusfits about as well
  3. Capsicumfits about as well
  4. Spinachfits about as well

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