Why it works: Celery and pepper match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 16,012 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Oyster Soup
Ingredients
Directions
Prepare
Scald 1 pint of milk in a double boiler.
Wash and cut up the celery, then boil it in 1 pint of boiling salted water.
In a bowl, combine the oysters with 1 cup of cold water and pick over them carefully.
Strain the oyster liquor into a saucepan and bring it to a boil, removing any scum.
Mash the cooked celery in the water it was boiled in and strain it into the oyster liquor, ensuring you have 1 pint of liquid.
Make the soup
Melt the butter and mix in the cracker crumbs, then add some of the milk until thin enough to pour into the oyster soup.
Add the mace and cook for 5 minutes.
Stir in the remaining milk and the oysters, cooking until the oysters are plump, about 1 minute.
Optionally, add 1/4 cup of hot cream.
Season with salt and pepper and serve immediately.

Mace and pepper barely smell alike, yet cooks put them together in 12,257 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
- Oysters
- Provide the main flavour and tender texture once cooked until plump.
- Milk
- Forms the creamy body of the soup and carries the flavour.
- Butter
- Adds richness and fat, and helps cook the cracker crumbs smoothly.
- Cracker crumbs
- Thicken the soup as they absorb liquid and swell when warmed with butter and milk.
- Celery
- Lends a fresh, vegetal aroma and savoury flavour to the cooking liquid.
The step that matters
Cooking the oysters. Oysters turn firm and rubbery if overcooked, so they should only be heated briefly until plump and then served right away.
Swap the mace
How well each one fits the dish's main ingredients (milk, celery, oyster, butter, pepper, cream):
- Parsleyfits better
- Nutmegfits better
- Tarragonfits better
- Macethe original
Fit is the average pairing score against milk, celery, oyster, butter, pepper, cream. Candidates are from the same food group and used in at least 100 recipes.
