To Dress Fish

Serve
Stew the fish gently and serve in a deep dish with the sauce and fried bread around it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- The main component, which is fried until crisp and then gently stewed in the sauce.
- Anchovies
- Add a salty, savoury depth that rounds out the sauce.
- Red port
- Adds sweetness and fruity depth, and its reduction thickens the sauce as it boils.
- Horseradish
- Contributes a sharp, pungent aroma and heat to the dressing.
- Lemon juice
- Adds acidity that brightens the sauce and balances the richness.
- Shallots
- Provide a mild aromatic base that softens and sweetens in the sauce.
The step that matters
Fry the fish until crisp and green, but do not overcook. Frying sets a crisp outer surface while the inside stays moist. Overcooked fish turns dry and firm, and it will not absorb the sauce well when stewed afterwards.
