Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Roe Omelette
Ingredients
Directions
Prepare the roe
Boil the roe in hot water with a little salt for 20 minutes.
Plunge the roe into ice-cold water until cold and firm.
Wipe the roe.
Break the roe into a granulated mass, removing skin and strings.
Mix the roe with 1 tablespoon of butter, 1 tablespoon of minced parsley, salt, and cayenne pepper.
Heat ½ cup of drawn butter in a saucepan.
Beat the roe mixture into the heated butter.
Set the saucepan in boiling water while you prepare the omelette.
Make and serve the omelette
Whip 6 eggs together with a little salt until light.
Pour the eggs into a frying pan with 1 tablespoon of simmering butter.
Shake the pan steadily until the omelette thickens.
Spread the roe mixture on half of the omelette.
Fold the other half of the omelette over the roe mixture.
Turn the folded omelette out onto a hot dish.
Garnish with parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Roe of shad
- Provides the main filling and rich flavour, set firm by boiling and chilling.
- Eggs
- Form the omelette structure, setting into a tender sheet around the filling.
- Butter
- Adds richness and carries the roe, while also keeping the omelette from sticking.
The step that matters
Beat the roe mixture into the heated butter. If the butter is too hot or the roe is added carelessly, the mixture can split or curdle, so it should be beaten in gradually to form a smooth, cohesive filling.
“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.
