OUR CULINARY ADVICE :

  • When fish is bought fresh, its skin should be shiny.
  • It is best to cook it quickly, at a high temperature.
  • Cold-smoked, it is delicious.
  • Marinate in a mixture of citrus fruit juice and fresh herbs.

Freezing will not alter its taste. It is, therefore, a very good conservation method.
