Why it works: Allspice and parsley match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 1,289 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Stewed Eels
Ingredients
Directions
Prepare
Wash and cut the eels into 2.5-inch pieces.
Cook the eels
In a pot, cover the eels with cold water and add salt, sliced onions, and allspice.
Boil slowly for 30 minutes.
Make the sauce
In a small saucepan, melt the butter over low heat. Stir in the flour until smooth.
Gradually add some of the boiling stock from the eels to the flour mixture until it forms a thick sauce.
Serve
Place the eels on a platter and pour the sauce over them. Garnish with chopped parsley.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- The main protein; they become tender and flaky as they simmer slowly in the stock.
- Butter
- Adds richness and flavor to the sauce base.
- Flour
- Thickens the stock into a smooth, thick sauce when cooked with the butter and liquid.
- Onion
- Flavors the cooking stock with sweetness and aroma as it simmers.
The step that matters
Make the flour and butter mixture smooth before adding stock. Flour clumps if it hits liquid unevenly. Cooking it briefly in butter and adding the hot stock gradually lets the starch disperse and thicken the sauce evenly.
Swap the onion
How well each one fits the dish's main ingredients (allspice, butter, flour, parsley):
- Shallotfits better
- Parsnipfits better
- Arrowrootfits better
- Onionthe original
Fit is the average pairing score against allspice, butter, flour, parsley. Candidates are from the same food group and used in at least 100 recipes.
