Why it works: Parsley and capers match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,550 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Grilled Salmon
Ingredients
Directions
Marinate
Place the salmon in a dish and pour the oil over it.
Sprinkle the salmon with salt, bay leaf, parsley, and scallions, then turn the salmon to coat and let it soak for some time.
Grill
Preheat the grill and place the salmon on it.
Turn the salmon and baste it with the seasoning occasionally.
Check the thickest part of the salmon; if still red, continue cooking.
Once cooked, turn the salmon onto a plate.
Remove the skin from the salmon.
Serve
Pour butter sauce over the salmon.
Sprinkle capers over the salmon before serving.

Butter and sauce barely smell alike, yet cooks put them together in 15,338 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
- Salmon
- Is the main protein; its flesh cooks and firms as the heat sets the proteins.
- Good oil
- Carries the seasoning over the fish and keeps the surface from drying out on the grill.
- Fine salt
- Seasons the flesh and helps it hold moisture while it soaks.
- Scallions
- Add mild onion aroma that infuses the oil and seasoning during the soak.
The step that matters
Checking the thickest part. Salmon goes from translucent to opaque as it cooks, and the thickest section lags behind the thin edges. Checking there prevents undercooking while the thin parts risk drying out.
Swap the parsley
How well each one fits the dish's main ingredients (salmon, butter, sauce, capers):
- Tarragonfits about as well
- Parsleythe original
- Dillfits less well
- Garlicfits less well
Fit is the average pairing score against salmon, butter, sauce, capers. Candidates are from the same food group and used in at least 100 recipes.
