Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 14,037 recipes mention both. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Sole Au Gratin
Ingredients
Directions
The book says “a fairly hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the fish
Skin the soles, remove the head and tail, trim neatly, and wash in plenty of water.
Make a light cut along the backbone of the soles.
Bake and finish
Lay the soles in a well-buttered fireproof dish, add water, and season with salt, pepper, and parsley.
Bake in a 400°F (200°C) oven for 6-8 minutes.
Pour the hot Sauce Chasseur over the soles, then sprinkle with bread crumbs and melted butter.
Return to the oven until fully cooked and the top is a bright brown color.
Serve with chopped parsley and a squeeze of lemon.

Sauce and butter share little aroma chemistry, yet 15,338 recipes mention both: they likely work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Soles
- Form the main body of the dish, cooking into tender, flaky fillets.
- Sauce chasseur
- Adds moisture and savory flavor, keeping the fish from drying as it bakes.
- Bread crumbs
- Form a crisp topping that browns in the oven under the butter.
- Melted butter
- Carries heat and encourages browning of the crumb topping, adding richness.
The step that matters
Return to the oven until fully cooked and browned. Fish cooks quickly and overbakes easily, turning dry and firm. Watch the fish closely while the topping browns so the flesh stays moist and flakes easily.
