Why it works: Lemon and watercress match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 579 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Sole, Mayonnaise
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
Fillet the soles and roll them up, securing with thread.
Season with pepper, coarse sea salt, and lemon juice.
Bake and finish
Bake at 400°F (200°C) for 8 minutes, basting with butter once or twice.
Let the fillets cool, then add a few drops of essence of anchovies on each.
Cover with thick mayonnaise sauce and garnish with chillies and watercress.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Soles
- Form the main protein that cooks gently and turns flaky when baked.
- Butter
- Adds fat and moisture while basting, helping the fish stay tender and browning the surface.
- Lemon juice
- Adds acidity that brightens the flavour of the fish and the sauce.
- Thick mayonnaise sauce
- Adds richness and a creamy coating that contrasts with the cooked fish.
The step that matters
Bake at 400°F (200°C) for 8 minutes, basting with butter once or twice. Fish proteins set quickly and dry out past the point of tenderness, so a short bake with butter basting keeps the fillets moist. Overbaking toughens the flesh and makes it crumble.

Fit is the average pairing score against pepper, butter, sauce, watercress. Candidates are from the same food group and used in at least 100 recipes.
