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 ↓
Eel in Aspic
Ingredients
Directions
Prepare the eel
Remove any small bones from the eel with a knife.
Sprinkle pepper, coarse sea salt, and chopped parsley over the eel.
Roll the eel up and tie it in a piece of muslin.
Poach and cool
Boil the eel in water with vinegar for 20 minutes.
Let the eel cool completely, then slice it.
Set in aspic
Arrange the best slices around the sides of a mold and place the rough pieces in the center.
Fill the mold with nearly cold aspic jelly.
Store in the larder until ready to serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eel
- Forms the main body of the dish, providing the flesh that is sliced and set in jelly.
- Aspic jelly
- Sets around the eel slices, holding them in a firm, clear gel that can be sliced and served.
- Vinegar
- Adds a sharp acidity to the poaching water, cutting the richness of the eel.
The step that matters
Fill the mold with nearly cold aspic jelly. Aspic is a gelatin-based liquid that sets as it cools. If it is too hot, it can melt or cloud the eel slices and prevent a clean set, while if it is too cold it may set before filling evenly and trap air or lumps around the fish.
Swap the parsley
How well each one fits the dish's main ingredients (pepper, vinegar):
- Tarragonfits better
- Dillfits about as well
- Parsleythe original
- Peppermintfits about as well
Fit is the average pairing score against pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
