Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
To Stew Cod
Ingredients
Directions
Prepare
Lay the cod slices in a large stew-pan without stacking them.
Season the cod with nutmeg, pepper, and coarse sea salt.
Add the sweet herbs, onion, white wine, and water to the pan.
Stew
Cover and simmer gently for 5–6 minutes.
Squeeze in the lemon juice, add the oysters and strained liquor, and the butter rolled in flour.
Add the mace, cover, and stew gently, shaking the pan often.
Serve
Remove the herbs and onion before serving, and pour the sauce over the cod.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod
- Forms the main body of the dish, cooking gently to become flaky and tender.
- Butter rolled in flour
- Flour thickens the cooking liquor into a silky sauce while butter adds richness.
- White wine
- Adds acidity and aroma to the cooking liquid, balancing the richness of the sauce.
- Oysters
- Contribute a briny, savoury flavour that enriches the sauce as they cook.
- Lemon juice
- Adds acidity that brightens the flavour and balances the richness of the butter.
The step that matters
Simmering the cod gently without stacking. Gentle heat and a single layer let the cod cook evenly and stay tender. Vigorous boiling or crowded pieces can toughen the fish and break it apart.
Swap the onion
How well each one fits the dish's main ingredients (nutmeg, pepper, white wine, lemon, oyster, butter, flour):
