Why it works: Mustard and vinegar are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 14,067 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Fresh Herrings
Ingredients
Directions
Prepare
Remove the heads and clean the herrings thoroughly.
Broil the herrings
Place them on a grill over a bright fire and broil for 10 to 12 minutes, depending on size.
Make the sauce and serve
For the sauce, knead 2 teaspoons of baked flour and 1 teaspoon of mustard flour with 3 ounces of butter.
Stir this mixture into ½ cup of boiling water and boil for 5 minutes.
Add 1 teaspoon of vinegar and serve the sauce hot with the herrings.

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
- Herrings
- Provide the main fish, which cooks quickly over high heat and carries the dish.
- Butter
- Adds richness and fat that emulsifies with the flour and water into a smooth sauce.
- Baked flour
- Thickens the sauce as it boils with the butter and water.
- Mustard flour
- Adds sharp, pungent mustard flavour to the butter sauce.
- Vinegar
- Adds acidity that brightens the rich butter and mustard sauce.
The step that matters
Broiling the herrings over a bright fire. Fish is delicate and dries out or sticks if overcooked or under-timed. Size changes how fast the flesh cooks through, so the 10 to 12 minute range must be checked against the fish in front of you.
Swap the mustard
How well each one fits the dish's main ingredients (butter, flour, vinegar):
- Shallotfits better
- Mustardthe original
- Chivefits about as well
- Cucumberfits about as well
Fit is the average pairing score against butter, flour, vinegar. Candidates are from the same food group and used in at least 100 recipes.
