Why it works: Parsley and arrowroot match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 137 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Boiled Smelts Another Way
Ingredients
Directions
Poach the smelts
In a small stewpan, combine salt, sugar, and parsley with enough water to cover the smelts.
Bring to a boil, then add the smelts and simmer for 5 minutes, covered.
Carefully remove the smelts and place them on a dish.
Pour the broth over the smelts.
Thicken the broth
If desired, mix arrowroot with a drop of cold water and add it to the broth when the smelts are half cooked.
Ensure the broth does not burn; there should be about three parts liquid remaining after cooking.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Smelts
- Provide the delicate fish that is gently cooked in the seasoned broth.
- Arrowroot
- Thickens the broth into a light, glossy sauce when heated.
The step that matters
Adding the arrowroot slurry. Arrowroot must be mixed with cold water first and added to the simmering broth; added dry or to a boil it clumps, and it thickens only when heated, not boiled hard for long.
Swap the arrowroot
How well each one fits the dish's main ingredients (smelt, sugar, parsley):
- Carrotfits better
- Horseradishfits better
- Parsnipfits better
- Arrowrootthe original
Fit is the average pairing score against smelt, sugar, parsley. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
