Why it works: Shallot and vinegar are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 2,374 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Pickled Fish in Vinegar
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Wash and clean the herrings, then remove the heads.
Dry the herrings well and cut them into thick pieces.
Pickle and bake
Pack the pieces closely in a jar and add the peppercorns, mace, shallot, bay leaf, vinegar, water, and salt.
Cover the jar tightly and bake in a cool oven at 300°F (150°C) for 1½ hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Herrings
- Form the main body of the dish, becoming tender and flaky during slow baking.
- Vinegar
- Acidifies the liquid, helping preserve the fish and giving it a sharp, tangy flavour.
- Salt
- Seasons the fish and liquid while helping firm the flesh.
- Shallot or onion
- Adds mild aromatic sweetness that mellows during the long, gentle bake.
The step that matters
Bake in a cool oven with the jar tightly covered. Low, gentle heat cooks the fish slowly so it becomes tender without breaking apart. A tight cover traps steam and liquid around the pieces, keeping them moist and evenly infused with the vinegar brine.
Swap the mace
How well each one fits the dish's main ingredients (shallot, vinegar):
- Tarragonfits better
- Capersfits better
- Parsleyfits better
- Macethe original
Fit is the average pairing score against shallot, vinegar. Candidates are from the same food group and used in at least 100 recipes.
