Why it works: Lemon and parsley 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 Steaks with Maitre-d’ Hotel Sauce
Ingredients
Directions
The book says “a moderate oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Prepare the fish
Wash the halibut and cut it into slices ½ inch thick.
Butter a baking dish and lay the fish slices in it.
Squeeze the juice of ½ lemon over the fish and sprinkle with pepper and salt.
Cover the fish with a well‑buttered paper.
Make the sauce
To make the Maitre-d' Hotel Sauce, melt the butter in a saucepan.
Add the finely chopped eschalot and cook gently for 10 minutes.
Mix in the flour, then gradually stir in the stock and milk.
Season with pepper and salt, then add the chopped parsley.
Remove from heat and stir in the lemon juice.
Bake and serve
Bake in a moderate oven (350°F / 175°C) for 10 to 15 minutes.
Lift the fish slices onto a hot dish.
Pour in the gravy from the fish and serve over the fish.
Pour the Maitre-d' Hotel Sauce over the fish to coat it well.
Garnish with fresh parsley and sprinkle with coralline pepper.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Halibut
- Forms the main protein that cooks through gently in the oven.
- Butter
- Adds richness and carries flavour, and keeps the fish from drying out.
- Flour
- Thickens the sauce by forming a starch-based structure with the melted butter.
- Milk
- Gives the sauce a creamy body and mild sweetness.
- Stock
- Supplies savoury depth to the sauce base.
- Lemon juice
- Adds acidity that brightens the fish and the sauce.
The step that matters
Making the flour-butter base and adding liquid. Cook the flour in the melted butter first, then add the stock and milk gradually while stirring. This prevents lumps and lets the starch thicken the sauce evenly.
