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 ↓
Breslin Baked Bluefish
Ingredients
Directions
Prepare
Split and bone the bluefish.
Place the fish on a well-buttered baking sheet or oven-proof platter.
Make the sauce
In a bowl, combine the parsley, creamed butter, capers, egg yolks, lemon juice, onion, vinegar, pickles, salt, and paprika.
Bake
Cook the fish for 20 minutes in a hot oven at 400°F (200°C).
Spread the mixture over the fish and continue baking until the fish is fully cooked.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bluefish
- Forms the main body of the dish and is cooked through in the oven.
- Egg yolks
- Emulsify with the butter and set when heated, giving the topping body and richness.
- Butter
- Adds fat and richness, keeping the fish moist while it bakes.
- Lemon juice
- Adds acidity that brightens the rich butter and egg topping.
- Capers
- Add a sharp, briny flavour that cuts through the richness of the fish.
The step that matters
Spreading the topping over the fish before baking the rest. The egg yolks in the mixture can curdle or cook unevenly if the topping is overheated or left too long at high heat, so it should be spread evenly and baked just until the fish is fully cooked.
Swap the onion
How well each one fits the dish's main ingredients (bluefish, parsley, butter, capers, egg, lemon, vinegar):
- Shallotfits better
- Mustardfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against bluefish, parsley, butter, capers, egg, lemon, vinegar. Candidates are from the same food group and used in at least 100 recipes.
