Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- Provide the main protein and meaty, rich flavour that the pie is built around.
- Meat stock
- Cooks the eels and forms the liquid base of the sauce, adding savoury depth and moisture.
- Mushroom ketchup
- Adds concentrated savoury, umami flavour to the sauce.
- Lemon juice
- Adds acidity that brightens the rich flavours of the stock and eels.
The step that matters
Stew the eels until thoroughly cooked. Eel must be cooked through before baking, since the crust only browns the top and the pie is not cooked long enough inside to fully set the fish. Stewing in stock ensures the flesh is tender and safe to eat.
Swap the lemon
How well each one fits the dish's main ingredients (meat, pepper, mushroom, ketchup):
- Lemonthe original
- Limefits about as well
- Red currantfits less well
- Avocadofits less well
Fit is the average pairing score against meat, pepper, mushroom, ketchup. Candidates are from the same food group and used in at least 100 recipes.
