Why it works: Parsley and sage match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,445 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Eels Stewed
Ingredients
Directions
Prepare the eels
Fry the eel pieces until they are half cooked and browned, then let them cool.
Stew
In a pot, combine beef gravy, onion, parsley, white pepper, salt, sage, and mace.
Add the eels to the gravy and stew until tender.
Stir in the chopped anchovies, mustard, walnut ketchup, and red wine.
Finish and serve
Alternatively, after stewing, add port wine and lemon juice, then strain and thicken with butter and flour.
Serve with sippets of toasted bread.

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, which becomes tender through the long stewing.
- Flour
- Thickens the strained sauce with butter so it becomes smooth and body-rich.
- Butter
- Adds richness and, worked with flour, helps thicken the finished sauce.
- Anchovies
- Add savoury depth and a salty, umami note to the gravy.
- Walnut ketchup
- Adds dark, tangy savouriness that deepens the sauce's flavour.
- Lemon juice
- Adds acidity that brightens the rich, savoury sauce.
The step that matters
Frying the eel pieces until half cooked and browned. Browning builds flavour through the Maillard reaction, and stopping at half cooked keeps the eels from toughening or falling apart before the long stew finishes them.
