Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Cut the conger eel into small pieces.
Remove the fillets from the haddock.
Chop the onion and add it to a pot with the eel, haddock, cloves, herbs, mace, and water.
Make the broth
Bring to a boil and simmer for 30 minutes.
Strain the broth and return it to the pot.
Finish
Stir in the cream and lemon juice.
Season with pepper and coarse sea salt to taste.
