Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mackerel
- Forms the main body of the dish, and its oily flesh carries the stuffing and broiling heat.
- Egg yolk
- Binds the stuffing so it holds together inside the fish while it cooks.
- Breadcrumbs
- Absorb moisture from the roe and yolk, giving the stuffing a firmer, less wet texture.
- Lemon peel
- Adds bright, aromatic citrus oils that cut through the richness of the fish.
- Roe (in the method)
- Adds richness and a creamy texture to the stuffing.
- Flour
- Dusted on the fish so the surface browns and helps the skin crisp under the broiler.
The step that matters
Broil the mackerel until cooked through. Fish cooks quickly and dries out easily under intense heat. Cooking until just opaque and flaky at the thickest part keeps the flesh moist while the stuffing sets and the surface browns.
Swap the nutmeg
How well each one fits the dish's main ingredients (egg, lemon, thyme, parsley, pepper, flour, butter):
- Marjoramfits better
- Tarragonfits better
- Sagefits better
- Nutmegthe original
Fit is the average pairing score against egg, lemon, thyme, parsley, pepper, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
