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 ↓
How to Cook Fresh Herring to Serve Cold
Ingredients
Directions
Prepare the fish
Remove bones from the herring.
Sprinkle the fish with coarse sea salt and black pepper.
Roll the fish in flour.
Assemble and bake
Butter a baking dish generously.
Place the rolled fish closely together in the dish and add pieces of butter on top.
Mix half vinegar and half water, then pour over the fish.
Bake until the liquid is fully absorbed.

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
- Flour
- Forms a light coating that helps the fish brown and holds seasoning.
- Butter
- Adds fat that carries flavour and promotes browning in the baking dish.
- Vinegar
- Adds acidity that gives the sauce a sharp, bright taste.
The step that matters
Baking until the liquid is fully absorbed. Baking must continue until the vinegar and water mixture is absorbed. Stopping early leaves excess liquid, while overbaking can dry the fish and make it tough.
“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.
