Our fish fingers (which are fish sticks here) are also breaded and I'm trying to think of whether or not battered frozen fish can be purchased... probably it can and I just don't remember.
Anyway, it doesn't matter because fish and chips (and by the way this is the only circumstance under which we refer to fries as chips) are only really good when bought freshly cooked.
There used to be a prominent restaurant chain here called, H. Salt Fish and Chips that I remember from childhood. They had the most amazing fish and chips which were served in newspaper wrapping, which seemed so much fun to me.
I haven't seen one in years, though.
Now, if I want fish and chips (really good fish and chips) I have to go to an actual restaurant like, Bone Fish Grill and pay $25 for a dinner plate.
