Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 27,039 recipes mention both. Both carry 2-nonenal, which smells fatty, green. The science ↓
The recipe
Ingredients
Contains: milk, wheat, shellfish (auto-detected from the ingredients and method; we can miss things, so check labels)
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 fish
Skin and fillet the sole.
Tie each fillet in a knot and place on a buttered baking sheet.
Sprinkle with pepper, coarse sea salt, and lemon juice.
Bake and finish
Cover with buttered paper and bake at 350°F (175°C) for eight minutes.
Prepare Hollandaise sauce.
Remove the fillets from the oven and pour the Hollandaise sauce over them.
Decorate with browned breadcrumbs or lobster coral.

Sauce and butter share little aroma chemistry, yet 15,317 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
- Sole
- Forms the delicate, flaky main body of the dish once cooked gently.
- Hollandaise sauce
- Adds richness and a smooth, creamy coating over the cooked fish.
- Butter
- Greases the baking sheet and paper so the fish does not stick and gains a little richness.
- Lemon juice
- Adds acidity that brightens the fish and balances the richness of the sauce.
The step that matters
Covering the fillets while baking. The buttered paper traps moisture so the delicate fish steams gently rather than drying out. Eight minutes at 350°F is short, so the fish can easily overcook if left uncovered or baked longer.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
