I know that salmons and herrings are two different species of fish.
I noted that the word kipper could mean salted herring, but also salted salmon. Why is the same word used to refer to two different fish in salt?
When I read in the menu Loch Fynne kippers, what are they, salmons or herrings? Is Loch Fynne just the place of origin (Scotland?) or does that refer to something particular? special species or a particular way of cooking them?
