Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓

Ingredients
Directions
Prepare the heads
Remove the eyes from the cod heads and wash them thoroughly.
Drain the heads.
Sprinkle a little coarse sea salt over the heads.
Let the salted heads sit for 1 to 2 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod heads
- Form the main body of the dish, holding their shape while cooking and browning.
- Flour
- Forms a thin dry coating that helps the surface brown and crisp when basted.
- Dripping or butter
- Adds fat that carries heat to the surface, promoting even golden browning and richness.
- 1 cup of the boiling liquid
- Serves as the base of the sauce, thickened with butter and flour for body.
- Lemon juice
- Adds acidity that brightens the rich butter sauce and balances its flavor.
The step that matters
Basting until lightly browned. Fat and flour must coat the surface evenly; too little heat or fat leaves pale, soggy skin, while excess heat can scorch the flour before the flesh is heated through.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
