Why oil matters

Canned anchovies spend years submerged in oil. During that time, there is a constant exchange of flavors between the fish and the oil. If the oil is of poor quality, it transmits rancid or chemical flavors to the anchovy. If it is high quality, the exchange is bidirectional: the oil absorbs the umami and salt from the anchovy, and the anchovy absorbs the fruitiness and polyphenols from the oil.

Type of oil Effect on anchovy Recommendation
Extra Virgin Olive Oil (EVOO) Enhances flavor, adds fruitiness ⭐⭐⭐⭐⭐ Optimal
Olive oil (virgin) Good preservation, neutral flavor ⭐⭐⭐⭐ Very good
Refined olive oil Neutral, preserves well ⭐⭐⭐ Acceptable
Sunflower oil Flat flavor, no beneficial exchange ⭐⭐ Avoid if possible

Types of oil and result

The best artisanal anchovies are exclusively packed in EVOO with a designation of origin. Mass-produced industrial anchovies usually use sunflower oil to reduce costs. This is one of the most important hidden differences between "cheap" and premium anchovies.

Some artisanal brands even specify the olive variety: Arbequina for a mild fruity flavor, Picual for intensity and long preservation, Hojiblanca for balance.

The packaging process

After curing in salt (8-18 months), artisanal anchovies go through:

  1. Partial desalting in running water
  2. Manual cleaning fillet by fillet
  3. Drying on absorbent paper
  4. Packing in a can or jar with the selected oil
  5. Minimum 2-3 months rest in oil before sale

Uses for leftover oil

The oil left in the can after consuming the anchovies is liquid gold. It's packed with umami flavor. Use it for:

  • Dressing salads (mixed with vinegar or lemon)
  • Sautéing vegetables or potatoes
  • As a vinaigrette base for cod and orange salads
  • Mixing into pasta sauces
  • Spread on toast with tomato

Frequently asked questions

Are anchovies in sunflower oil worse than those in olive oil?
Not necessarily worse in terms of the anchovy's quality itself, but the final result is different. Sunflower oil does not add anything to the anchovy, and the exchange of flavors is much less beneficial. An excellent anchovy in sunflower oil can be worse than one in EVOO if the oil contributes unwanted flavors. And the leftover sunflower oil has no interesting culinary uses.
Can you change the oil of anchovies at home?
Yes: drain the anchovies from their original oil, place them in a glass jar, and cover them with quality EVOO. Let them rest for 24-48 hours in the refrigerator. The result significantly improves anchovies packed in low-quality oil. It's a trick widely used by chefs.
