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, cooking to flaky, tender flesh under the heat.
- Butter
- Adds fat that keeps the herb stuffing moist and rich as the fish cooks.
- Flour
- Binds the butter and chopped herbs together into a stuffing that holds its shape.
- Fennel
- Contributes a mild aniseed aroma that flavours the fish from within.
The step that matters
Broil over a clear, slow fire until cooked through. Fish cooks quickly and dries out easily. A slow, steady heat cooks the thick, stuffed centre through without scorching the skin, while the butter in the stuffing keeps the flesh moist.
Swap the mint
How well each one fits the dish's main ingredients (fennel, parsley, butter, flour, pepper):
- Tarragonfits better
- Thymefits better
- Dillfits better
- Mintthe original
Fit is the average pairing score against fennel, parsley, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
