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 ↓
Cracker Soup
Ingredients
Directions
Make the broth
Put the meat, onion, and bones in the cold water and cook slowly for two hours.
Strain the soup and cool it, removing all fat.
Return the broth to the heat.
Skim the broth as it heats.
Season the broth.
Soak the crackers
Salt and pepper the crackers in a bowl.
Pour the boiling milk over the crackers and cover tightly.
Set the bowl in boiling water for half an hour.
If the milk is not fully absorbed by the crackers, strain it out.
Combine and serve
Carefully place the crackers in a tureen.
Stir the flour and butter mixture and parsley into the soup.
Boil the mixture for one minute.
Pour the mixture over the crackers.
Cover the tureen and let it sit in hot water for ten minutes before serving.

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
- Boston crackers
- Soak up the milk and broth, forming the body and thickness of the soup.
- Milk
- Softens the crackers and adds creamy richness and mild sweetness to the soup.
- Butter
- Adds fat and richness, carrying flavor and giving the soup a smooth mouthfeel.
- Flour
- Thickens the butter mixture so it lends body to the soup when stirred in.
- Mutton
- Gives the broth its meaty flavor and depth as it simmers with the bones.
The step that matters
Skimming the broth as it heats. Fat and fine impurities rise to the surface of a simmering broth. Removing them keeps the soup clean-tasting and prevents a greasy texture.
Swap the mace
How well each one fits the dish's main ingredients (mutton, milk, butter, flour, pepper, onion, parsley):
- Thymefits better
- Marjoramfits better
- Garlicfits better
- Macethe original
Fit is the average pairing score against mutton, milk, butter, flour, pepper, onion, parsley. Candidates are from the same food group and used in at least 100 recipes.
