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 ↓
Fish Baked in Vinegar
Ingredients
Directions
The book says “a very slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the fish
Wash and clean the fish thoroughly in cold water.
Cut the fish into thick pieces.
Pack the jar
Lay the pieces close together in a stone jar with the peppercorns and salt.
Add the blade of mace and bay leaf.
Peel the shallot.
Add the shallot to the fish, adjusting the amount to taste.
Pour the vinegar into the jar.
Tightly cover the jar with brown paper secured with string.
Bake
Place the jar in a slow oven at 300°F (150°C) to bake for two hours, or leave it in a baker's oven overnight.

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 becomes firm and tender as it cooks slowly in the vinegar.
- Vinegar
- Adds acidity that flavours the fish and helps preserve it during the long, slow cook.
- Shallot
- Adds a mild, sharp onion aroma that mellows and infuses the fish during baking.
The step that matters
Covering the jar tightly. A tight cover with brown paper and string traps moisture and keeps the vinegar and spices concentrated, so the fish cooks gently in its own liquid instead of drying out in the slow oven.
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.
