Why it works: Onion and vinegar are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 18,226 recipes. Both carry acetic acid, which smells sour, vinegar. The science ↓
Sardines As Norwegian Anchovies
Ingredients
Directions
Prepare the sardines
Open the tin of sardines and remove the fish one by one.
Place the sardines on a dish and wipe them free from oil.
Tip the dish slightly and pour hot water over the sardines to remove the fishy oil.
Dry the sardines with a cloth.
Layer and marinate
In a clean earthenware pot, layer sliced onion, bay leaf, and peppercorns at the bottom.
Add a layer of sardines and repeat until the pot is filled.
Pour a mixture of 1 tablespoon vinegar to 4 tablespoons oil over the sardines to cover them.
Let the sardines marinate for a few days before serving.

What each ingredient does
- Sardines
- Form the main body of the dish, carrying the flavour of the marinade.
- Vinegar
- Adds acidity that sharpens the flavour and helps firm the fish during marinating.
- Oil
- Covers the fish, keeping it moist and sealed from air while it marinates.
- Onion
- Adds sweetness and aromatic flavour that penetrates the fish as it marinates.
The step that matters
Layering and covering the sardines. The sardines must be fully covered by the vinegar and oil mixture so no fish is exposed to air, which keeps the marinade even and reduces spoilage risk during the days of marinating.
