Why it works: Carrot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Baked Halibut Slices
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the fish
Wipe the halibut slices and place them in a buttered granite pan.
Sprinkle with salt and pepper, then add the carrot, onion, parsley, bay leaf, peppercorns, and lemon juice.
Pour the boiling water over the fish and bake for 25 minutes at 400°F (200°C), basting every 5 minutes.
Serve and make the sauce
Remove the fish from the oven, arrange on a hot serving dish, and remove the skin and bones.
Sauté the mushroom caps in butter for 5 minutes and place them on top of the fish.
For the sauce, melt 2 tablespoons of butter, add 2 tablespoons of flour, and gradually stir in the liquor from the pan until smooth.
Strain the sauce, season with salt if needed, and slowly mix in the beaten egg yolk and cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Halibut
- Forms the main body of the dish, cooked gently in the steam of the pan liquid.
- Flour
- Thickens the butter and pan liquor into a smooth sauce body.
- Egg yolk
- Enriches and thickens the sauce when mixed in gently at the end.
- Cream
- Adds richness and a smoother, silkier texture to the sauce.
- Butter
- Adds fat and rich flavour to the sauce and sautéed mushrooms.
The step that matters
Adding the egg yolk and cream. Egg yolk thickens through gentle heat; if the sauce is too hot when it is added, the yolk can scramble and turn grainy. Mixing slowly and off the heat keeps it smooth.
Swap the onion
How well each one fits the dish's main ingredients (pepper, carrot, parsley, lemon, mushroom, butter, sauce):
- Shallotfits better
- Capsicumfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against pepper, carrot, parsley, lemon, mushroom, butter, sauce. Candidates are from the same food group and used in at least 100 recipes.
