Why it works: Lime and spinach match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 213 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓
Kippered Seer-Fish Omelette
Ingredients
Directions
Cure and smoke the fish
Split, wash, and dry the seer-fish with a cloth.
Rub in coarse sea salt, sugar, and lime juice.
Repeat the rubbing the next day.
Hang the fish over a fire with damp straw to smoke it.
After smoking, hang it in the cook-room over the fire until ready to serve on the third evening.
Prepare the omelette
If using roe, soak and boil until tender.
Prepare the omelette with butter and add optional ingredients as desired.
Serve the omelette on a bed of tomato puree, green peas puree, or spinach puree, and top with grated cheese.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Seer-fish
- Forms the main body of the dish and carries the smoky, salted flavour.
- Coarse sea salt
- Draws moisture out of the fish and seasons it during curing.
- Sugar
- Balances the salt and promotes browning on the fish surface.
- Lime juice
- Adds acidity that brightens the flavour of the cured fish.
- Butter
- Adds fat and richness to the omelette and helps it brown lightly in the pan.
- Grated cheese
- Adds savoury flavour and browns on top when the dish is finished.
The step that matters
Repeat the rubbing the next day. Salt and sugar must penetrate the flesh gradually. A second rub reinforces the cure so the fish is evenly seasoned and firm before smoking.
Swap the tomato
The recipe marks tomato as optional. How well each one fits the dish's main ingredients (fish, sugar, lime, butter, cheese, peas, spinach):
- Lettucefits better
- Asparagusfits better
- Sweet potatofits better
- Tomatothe original
Fit is the average pairing score against fish, sugar, lime, butter, cheese, peas, spinach. Candidates are from the same food group and used in at least 100 recipes.
