Which supermarket was this ? Never see anything like this in the local Tescos.

I suggest trying to find a farm shop. I use one, and not only is the price
much cheaper than the supermarket, but the taste is superb. Even though they
don't make any specific claims about organic production, just saying that the
meat is from local farms, the taste is so much better, that I'm convinced of
it's superiority. The pork and chicken, in particular, taste as if they come
from completely different species from the supermarket variety.
