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 ↓
White Asparagus Soup
Ingredients
Directions
Make the stock
Crack the bones into splinters and chop the meat.
Combine the bones, chopped meat, and asparagus stalks with water in a pot, then cover the pot.
Cook gently for 3 hours.
Strain the mixture.
Cool to let the grease rise, then skim off the fat.
Return the strained liquid to the pot with seasoning and reserved asparagus heads.
Boil slowly for an additional 20 minutes.
Thicken and serve
Heat the milk in a separate pot.
Stir in the cornstarch and boil for 1 minute to thicken.
Pour the thickened milk into a tureen over the diced fried bread.
Stir in the boiling soup.
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Asparagus
- Supplies the main flavour and the body of the soup, with the stalks cooked into the stock.
- Milk
- Adds richness and a creamy texture to the finished soup.
- Cornstarch
- Thickens the milk as it boils, giving the soup a smoother, heavier body.
The step that matters
Boil the milk and cornstarch for 1 minute. Cornstarch only thickens fully once it reaches a boil and its starch granules swell. Boiling briefly thickens the milk; stopping early leaves it thin and floury-tasting.
Swap the parsley
How well each one fits the dish's main ingredients (asparagus, milk, pepper, bread, meat):
- Thymefits about as well
- Parsleythe original
- Celeryfits about as well
- Nutmegfits about as well
Fit is the average pairing score against asparagus, milk, pepper, bread, meat. Candidates are from the same food group and used in at least 100 recipes.
