Why it works: Parsley and pepper 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 ↓
To Boil Prawns
Ingredients
Directions
Boil the prawns
Add a handful of salt to a pot of boiling water.
When the water is boiling hard, add the prawns.
Boil the prawns for 15 minutes.
Remove the prawns and place them on a sieve to drain.
Wipe the prawns with a dry cloth and set aside until completely cold.
Arrange and serve
Arrange a handful of curled parsley in the center of a dish.
Place one prawn on top of the parsley and arrange the others around it with tails facing out.
Garnish with additional parsley.
Serve with a mixture of salt, cayenne, sweet oil, mustard, and vinegar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Prawns
- Cook through in boiling water, becoming firm and opaque, and are served cold as the main dish.
- Vinegar
- Adds acidity that brightens the flavour of the rich seafood in the accompanying sauce.
- Sweet oil
- Adds fat and smoothness to the accompanying sauce, carrying flavour across the palate.
- Mustard
- Adds sharp, pungent heat to the accompanying sauce that cuts through the richness of the prawns.
The step that matters
Boil the prawns for 15 minutes. Boiling too long toughens prawn flesh as proteins over-tighten and squeeze out moisture, so timing must be watched closely to keep them tender and juicy.
Swap the parsley
How well each one fits the dish's main ingredients (pepper, mustard, vinegar):
- Tarragonfits better
- Dillfits better
- Capersfits better
- Parsleythe original
Fit is the average pairing score against pepper, mustard, vinegar. Candidates are from the same food group and used in at least 100 recipes.
