Why it works: Parsley and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Skate Soup
Ingredients
Directions
Prepare the skate
Clean the skate and hang it in the open air for a day.
Cut the skate into small fillets and place the trimmings and head in a saucepan with the fish stock or water.
Make the broth
Simmer gently for an hour, removing scum as it rises.
Add the onion, turnip, parsley, and celery, and simmer until the liquid reduces to one quart.
Finish and serve
For the first option, thicken the broth with brown thickening, add the fillets, and simmer until cooked. Flavor with ketchup, sherry, pepper, and salt.
For the second option, add the vermicelli and cook until tender, then mix in the cream beaten with the egg yolk, stirring over low heat for 8-10 minutes without boiling.
Serve the soup very hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Skate
- Provides the main flesh and flavor of the soup, with the trimmings and head enriching the broth.
- Cream
- Adds richness and a smooth, silky body to the finished soup.
- Egg yolk
- Thickens the cream mixture gently, giving body without boiling.
- Vermicelli
- Adds starch and body to the soup as it cooks until tender.
- Turnip
- Contributes subtle sweetness and body to the simmered broth.
The step that matters
Adding the cream and egg yolk. Egg yolk can curdle and turn grainy if it boils. Stirring over low heat keeps the mixture smooth and thickens it gently.
Swap the onion
How well each one fits the dish's main ingredients (fish, turnip, parsley, celery, cream, egg, ketchup):
