Ever since we moved to our current house over 20 years ago, we have had a local business that sells boxes of beautiful fresh frozen fish, ring me regularly and delivers my order to the door.
The business has changed hands a few times and has now been incorporated into a company that does, top quality ready meals. I still just buy the fish. It is not cheap but it is better than any fish I have ever seen in a supermarket or frozen food retailer.
We did have a fresh fish company come round once and I tried their fish out and lived to regret it. It was not that fresh and I threw a lot of it away.
