I was so surprised to find it there, but very happy! I think someone else posted recently that they found it at Co-op, so perhaps it'll be everywhere before too long.
It was at the deli with the 'real' cheeses, not in the cheese/butter/etc section. And guess where it's made? North Wales! I had a laugh about that. Oh, and they spelled it Monteray. But still, it was nice to see.
I just tasted a bit, and I honestly don't think it's all that great. I think I've completely forgotten what American Monterey Jack tastes like, so I can't really compare properly. It's very mild, and I prefer a sharper cheese.
