Arctic char are closely related to salmon and trout, sharing many characteristics. Its distinctive pink flesh has a firm succulent texture with a delicate flavour.
I spotted these while shopping online the other day and was surprised at how cheap they were - especially as they are from their "Finest" range. They weren't advertised as a special offer or anything so it may have just been a store specific misprice (although I do hope not!!) Hopefully someone can confirm for me whether or not this is the case soon enough!
They are nice chunky fillets and they taste lovely, just as good as salmon or trout, we had them last night for dinner and were very impressed. In fact I will be popping back to stock up very soon...!
