Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the dish, cooking gently under cover to stay moist.
- Breadcrumbs
- Form a crust over the fish that helps it brown and hold moisture.
- Clarified butter
- Adds richness and helps the surface brown during cooking.
- Light wine
- Adds acidity and aroma that season the fish as it cooks.
- Mushrooms
- Contribute moisture and savory flavor to the dish.
The step that matters
Cook over a slow charcoal fire, covered. Gentle, steady heat cooks the fish through without drying or burning the breadcrumb crust. Covering the dish traps steam so the fish stays moist. Renewing the charcoal keeps the heat even over the full cooking time.
Swap the onion
How well each one fits the dish's main ingredients (fish, egg, parsley, mushroom, vinegar, butter, wine):
- Shallotfits better
