Why it works: Parsley and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Oyster Croquettes
Ingredients
Directions
Prepare the oysters
Parboil the oysters until the edges curl, then drain and chop them.
Make the filling
Melt the butter in a pan, add the flour, and slowly pour in the oyster liquor and cream.
Stir in the parsley, cayenne, celery salt, mace, salt, and beaten egg yolks.
Cook for 2-3 minutes.
Add the chopped oysters to the mixture and let it cool.
Shape, coat and fry
Shape the mixture into croquettes, then roll in cracker crumbs, dip in beaten egg, and coat again in crumbs.
Fry the croquettes in hot oil until golden brown, then drain on paper towels.

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
- Oysters
- Provide the main flavor and the bulk of the filling, cooked briefly so they hold their shape.
- Butter and flour
- Form a roux that thickens the liquids into a binder that holds the croquettes together.
- Oyster liquor and cream
- Supply moisture and richness, turning the roux into a smooth, creamy filling.
- Egg yolks
- Add richness and help bind the filling as it sets when cooked.
- Cracker crumbs
- Form a crisp outer coating that browns when fried.
The step that matters
Let the filling cool before shaping. A warm, soft filling is too loose to hold its shape and can split or leak in the oil. Cooling lets the starch and egg set so the croquettes keep their form while frying.
Swap the mace
How well each one fits the dish's main ingredients (oyster, butter, flour, cream, parsley, pepper, celery):
- Tarragonfits better
- Nutmegfits better
- Thymefits better
- Macethe original
Fit is the average pairing score against oyster, butter, flour, cream, parsley, pepper, celery. Candidates are from the same food group and used in at least 100 recipes.
