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 ↓
Fish Cream Sauce, for Croquettes Axd Patties
Ingredients
Directions
Make the sauce
Scald the cream in a saucepan.
Melt the butter in a large saucepan until bubbling.
Add the cornstarch and stir until well mixed.
Gradually add one-third of the cream and stir until it boils and thickens.
Continue adding more cream until the sauce is perfectly smooth.
Season and finish
Add the seasonings and mix while hot with the meat.
The sauce should be thick, similar to drop batter.
If desired, add one beaten egg for extra creaminess.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cream
- Forms the liquid base that thickens into a smooth, rich sauce.
- Cornstarch or flour
- Thickens the sauce as its starch swells with heat when stirred into the liquid.
- Butter
- Adds fat for richness and smooth mouthfeel, and helps the starch blend in.
- Egg
- Adds richness and extra body when stirred into the finished sauce.
The step that matters
Gradually add one-third of the cream and stir until it boils and thickens. Adding liquid slowly while stirring keeps the starch dispersed so it thickens evenly without lumps. Starch needs to reach a boil to fully swell and set the sauce.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (cream, butter, flour, white pepper, celery, pepper, egg):
- Leekfits better
- Spinachfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against cream, butter, flour, white pepper, celery, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
