Why it works: Cream and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Fish Creams
Ingredients
Directions
Prepare the fish
Boil the halibut and pick it apart.
Mash the halibut finely.
Mix the egg whites, salt, pepper, and cream into the mixture thoroughly.
Pack the mixture into small molds and steam for 20 minutes.
Turn the molds onto a heated dish.
Make the sauce
For the sauce, cream together the butter and flour.
Gradually add the boiling water and let it boil.
Remove from heat and stir in the egg yolk.
In another pan, combine the onion, bay leaf, and vinegar and reduce by half over heat.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Halibut
- Forms the main body of the creams, giving them their flaky, tender bulk.
- Egg whites
- Set when steamed, giving the mixture structure and a light, firm texture.
- Cream
- Adds moisture and softness, keeping the steamed creams tender rather than dry.
- Butter
- Enriches the sauce with fat, adding richness and a smooth mouthfeel.
- Flour
- Cooked with butter to form a roux that thickens the boiling water into a sauce.
- Egg yolk
- Added off the heat to enrich and thicken the sauce without scrambling.
The step that matters
Stir in the egg yolk off the heat. Egg yolk thickens through gentle heat. If the sauce is still boiling when the yolk goes in, the proteins can scramble, leaving lumps and a grainy texture instead of a smooth, enriched sauce.
Swap the onion
How well each one fits the dish's main ingredients (egg, pepper, cream, butter, flour, vinegar):
- Shallotfits better
- Chivefits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against egg, pepper, cream, butter, flour, vinegar. Candidates are from the same food group and used in at least 100 recipes.
