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 ↓
Puree Asparagus
Ingredients
Directions
Prepare the asparagus
Wash the asparagus.
Parboil the asparagus for 4 minutes, then immerse it in cold water and drain it.
Melt the butter in a saucepan.
Toss the asparagus gently over heat, then season it with salt, pepper, nutmeg, and a little sugar.
Add enough broth to cook the asparagus thoroughly along with the parsley.
Boil the asparagus until tender.
Make the puree
Pound the asparagus through a colander.
Combine the puréed asparagus with thickened chicken broth or cream in a saucepan.
Heat the mixture while stirring until it boils.
Reduce heat and simmer for 25 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Asparagus
- Forms the main body of the puree and gives it its flavour and green colour.
- Butter
- Adds richness and a smooth, silky mouthfeel to the finished puree.
- Thickened chicken broth or cream
- Supplies liquid and body, giving the puree a smooth, spoonable consistency.
- Egg yolks
- Thicken the puree gently and add richness when stirred in at the end.
The step that matters
Adding the egg yolks. Egg yolks thicken by gentle heat. If the mixture is kept at a hard boil after the yolks go in, they can scramble and curdle, leaving the puree grainy instead of smooth.

Fit is the average pairing score against butter, pepper, nutmeg, sugar, chicken, parsley, egg. Candidates are from the same food group and used in at least 100 recipes.
