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 ↓
Halibut Steak a LA Flamande
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Butter the bottom of a roasting pan and sprinkle with chopped onion, salt, and pepper.
Place the halibut steak on top.
Season and bake
Brush the steak with the egg yolk.
Sprinkle with chopped onion, parsley, salt, and pepper.
Pour lemon juice over the fish.
Dot with small pieces of butter.
Bake for 30 minutes, basting frequently.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Halibut steak
- Forms the main body of the dish, cooking through gently in the oven.
- Butter
- Adds richness and moisture, and helps the fish stay tender as it bakes.
- Egg yolk
- Brushed on the steak, it adds richness and helps the surface set and brown slightly.
- Onion
- Lies under and over the fish, adding sweetness and aroma as it softens in the pan juices.
- Lemon juice
- Adds acidity that brightens the mild flavor of the fish.
The step that matters
Basting frequently during the 30-minute bake. Halibut is lean and dries out easily in dry oven heat. Regular basting with the buttery pan juices keeps the surface moist and the flesh tender, and it stops the fish from overcooking before it is done.
Swap the onion
How well each one fits the dish's main ingredients (butter, pepper, egg, parsley, lemon):
- Shallotfits better
- Spinachfits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against butter, pepper, egg, parsley, lemon. Candidates are from the same food group and used in at least 100 recipes.
