Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set as they heat, thickening the mixture into a soft, custard-like base.
- Milk
- Dilutes the eggs and keeps the mixture creamy and tender as it thickens.
- Butter
- Adds richness and a silky mouthfeel, and helps keep the eggs from sticking.
- Cold cooked fish
- Provides the main flavour and body, folded into the thickening egg mixture.
The step that matters
Stirring the eggs and milk over medium heat. Egg proteins set quickly and can turn grainy or curdled if overheated. Gentle heat and constant stirring keep the mixture smooth and thickened rather than scrambled.
Swap the parsley
How well each one fits the dish's main ingredients (fish, egg, butter, pepper, milk):
- Parsleythe original
- Nutmegfits about as well
- Tarragonfits less well
- Cinnamonfits less well
Fit is the average pairing score against fish, egg, butter, pepper, milk. Candidates are from the same food group and used in at least 100 recipes.
