Why it works: White wine and vinegar are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 1,776 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Collared Eels
Ingredients
Directions
Prepare the eels
Skin and bone the eels.
Season the eels with mace, chopped eschalots, pepper, coarse sea salt, and pimento.
Roll up the eels and tie them firmly with tape.
Cook
Place the eels in a stew-pan with veal stock, white wine, and vinegar.
Let them simmer until cooked through.
Transfer the eels to a dish and skim off the fat.
Season the cooking liquid with salt.
Make the jelly and serve
Simmer the liquid with the egg whites for a few minutes to clarify.
Strain the liquid through a cloth and boil until it thickens into a jelly when cold.
Remove the tape from the eels and pour the jelly over the fish.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Mace and pepper barely smell alike, yet cooks put them together in 12,257 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- Form the main body of the dish, cooked gently until tender and set in jelly.
- Veal stock
- Supplies the liquid that cooks the eels and provides the gelatin that sets the jelly.
- Egg whites
- Collect impurities as they heat, clarifying the cooking liquid into a clear jelly.
- White wine
- Adds acidity and aroma to the cooking liquid, balancing the richness of the fish.
- Vinegar
- Adds sharpness to the cooking liquid, balancing the richness of the fish and stock.
The step that matters
Clarifying the cooking liquid with egg whites. Egg whites coagulate as they heat and trap cloudy particles. If the liquid is not simmered gently or strained carefully, the jelly stays cloudy and loses its clear appearance.
Swap the mace
How well each one fits the dish's main ingredients (pepper, veal, white wine, vinegar, egg):
- Tarragonfits better
- Parsleyfits better
- Marjoramfits better
- Macethe original
Fit is the average pairing score against pepper, veal, white wine, vinegar, egg. Candidates are from the same food group and used in at least 100 recipes.
