Tips

986 mg of potassium: no other fish in the database provides as much. A 150 g portion covers nearly three quarters of the reference intake. Potassium contributes to blood pressure regulation.

Worth mentioning if you have kidney failure. Potassium then has to be limited, and a fish at this level deserves to be counted in the total.

It is a semi-oily and very affordable fish. At 0.45 g of omega-3, it has less than a sardine but far more than a white fish. At a comparable price, it is an excellent compromise.

Remove the line of spiny scales. It runs along the flank and comes away with a knife. It is the only special preparation this fish needs.

Grilled or in escabeche. Like all oily fish, it needs no added fat: its own fat is enough. Lemon and vinegar suit it particularly well.
