Why it works: Mustard and lettuce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,356 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ingredients
Directions
Poach the fish
Boil the fish for about 10 minutes, then remove and let it cool on a dish.
Make the sauce
In a bowl, mix the salt, beaten egg whites, mustard, and cornstarch, then add the egg yolks and beat until combined.
Assemble and serve
Cover the cooled fish with the mixture and pour the beef broth over it.
Decorate the fish with the hard boiled eggs, cut into quarters.
Garnish with lettuce and radish before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped or beaten whites add lightness and help the mixture set and hold its shape.
- Egg yolks
- Yolks add richness and emulsifying fat, giving the coating a smooth, creamy body.
- Cornstarch
- Starch thickens the mixture as it heats, giving the coating a stable, sliceable body.
- Mustard
- Mustard adds sharp flavor and helps emulsify the fats in the sauce.
- Hard boiled eggs
- Cooked whites and yolks add firm texture and mild richness as a garnish.
The step that matters
Beating the egg mixture until combined. Egg proteins and starch must be evenly blended before the mixture is spread over the fish, otherwise lumps and uneven setting can result. Thorough mixing gives a smooth, uniform coating.
Swap the radish
How well each one fits the dish's main ingredients (fish, egg, mustard, beef, lettuce):
- Horseradishfits better
- Chivefits better
- Asparagusfits better
- Radishthe original
Fit is the average pairing score against fish, egg, mustard, beef, lettuce. Candidates are from the same food group and used in at least 100 recipes.
