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 ↓
Crab Soup
Ingredients
Directions
Make the broth
Take one pint water, add a little onion, three or four blades of mace, a little parsley, cayenne pepper and salt. Let them come to a boil.
Finish and serve
Then add one quart picked crabs, one quart rich milk and cream half and half, one-quarter pound butter rubbed into a tablespoonful flour. Stir all into the crab.
Let it come to a good boil and send it hot to the table.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Picked crabs
- Provide the main protein and sweet, savoury flavour of the soup.
- Rich milk
- Adds body and creaminess, giving the soup a smooth, rich texture.
- Butter
- Adds richness and fat, rounding out the flavour and softening the texture.
- Flour
- Rubbed into the butter to thicken the soup slightly as it heats.
The step that matters
Bringing the soup to a boil after adding the milk and flour-butter mixture. Milk can scorch or curdle if overheated, but the flour needs a full boil to cook out its raw taste and reach full thickness. Stir steadily and watch closely to keep the soup smooth.
Swap the mace
How well each one fits the dish's main ingredients (crab, milk, butter, flour, parsley, pepper):
- Nutmegfits better
- Thymefits better
- Tarragonfits better
- Macethe original
Fit is the average pairing score against crab, milk, butter, flour, parsley, pepper. Candidates are from the same food group and used in at least 100 recipes.
