Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Red Herrings Grilled
Ingredients
Directions
Prepare the herrings
Split the herrings lengthwise and remove the heads and tails.
Scald the herrings in boiling water, then drain them.
Coat and broil
Moisten the herrings with melted butter and sprinkle bread crumbs over them.
Baste the herrings with more butter and add another layer of bread crumbs.
Sprinkle fine herbs on top, then broil the herrings.
Moisten with oil or melted butter before serving hot, seasoned with pepper and herbs.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Red herrings
- Provide the main fish that cooks through and carries the crumb topping.
- Melted butter
- Adds moisture and richness, helping the crumbs brown under the broiler.
- Bread crumbs
- Form a crisp, golden crust on top of the fish when broiled.
The step that matters
Broiling the herrings. Broil until the crumbs are golden and the fish is opaque and flakes easily. Too little heat leaves the crust pale and the fish underdone, while too long dries the flesh and scorches the crumbs.
Swap the parsley
How well each one fits the dish's main ingredients (butter, bread, pepper):
- Parsleythe original
- Sagefits about as well
- Thymefits less well
- Nutmegfits less well
Fit is the average pairing score against butter, bread, pepper. Candidates are from the same food group and used in at least 100 recipes.
