Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
The Plain Red Herring
Ingredients
Directions
Prepare
Choose a firm, fresh red herring and wipe it clean.
Soak the herring in lukewarm water for a few hours if it is too salty, then dry it with a cloth.
Make a few incisions in the back of the herring or slightly split it.
Dust the herring with flour.
Grill and serve
Place the herring on a gridiron about 6 inches over a clear fire.
Turn the herring often and cook for about 5 minutes, depending on its size.
Mix butter with a little mustard and either place it inside the herring or rub it over the top before serving.

Flour and butter 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
- Red herring
- Forms the main body of the dish and carries the smoky, grilled flavour.
- Flour
- Dusting helps the surface dry and brown lightly over the fire.
- Butter
- Adds richness and moisture as it melts over the hot fish.
- Mustard
- Adds sharp, pungent flavour that cuts through the richness of the butter and fish.
The step that matters
Turning the herring over the fire. Turning often keeps the fish from scorching on the hot side while the thick parts cook through. Watching the heat matters because the fish is cooked quickly over a clear fire.
Swap the mustard
How well each one fits the dish's main ingredients (flour, butter):
- Shallotfits better
- Leekfits better
- Arrowrootfits better
- Mustardthe original
Fit is the average pairing score against flour, butter. Candidates are from the same food group and used in at least 100 recipes.
