Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Salmon Trout, with Truffles
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the trout
Scale and gut the salmon trout, then wash and dry it inside.
Chop the truffles.
Pound them in a mortar with the softened bread crumbs and butter.
Season the mixture with salt, pepper, and chopped parsley.
Fill the trout with this preparation.
Place the trout in a buttered baking dish.
Season with salt.
Baste with butter.
Bake
Bake in a preheated oven at 350°F (175°C).
Baste often for 12 minutes.
Add white wine and melted glaze to the dish.
Boil the liquid.
Return the dish to the oven.
After 15 minutes, check if the trout is done.
Transfer it to another dish.
Make the sauce and serve
Dilute fish stock with a little white wine.
Boil.
Thicken with kneaded butter.
Add chopped raw truffles.
Boil for 2 more minutes.
Finish with fresh butter, lemon juice, and chopped parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon trout
- Forms the main body of the dish, cooked whole and gently baked until done.
- Truffles
- Add a distinctive earthy aroma that perfumes both the filling and the sauce.
- Bread crumbs
- Absorb butter and juices, giving the filling a soft, moist body.
- Butter
- Adds richness and moisture, carrying flavour through the filling and basting the fish.
- White wine
- Adds acidity that brightens the sauce and helps lift the flavour of the pan juices.
The step that matters
Checking the trout for doneness. Whole fish can dry out or stay underdone at the thickest point, so checking after the set time and before the sauce is built helps keep the flesh moist and fully cooked.
