Mackerel Fillets in White Wine (Slideshow version)
Stage 2/6 : 7 min.
Put the fish into a pan of cold salted water and put this on low heat.Cook the mackerel at a gentle simmer. Ideally, use an thermometer stuck into the middle of the fish and stop cooking when the temperature reaches 140°F (60°C).
If you don't have a thermometer, cook for 7 minutes, counting from when the water starts to simmer.
