In response to kosher doc's mention in the thread about the imported Greek feta with a fraudulent OU, I just want to say that the mail order Cabot Cheddar he mentioned is a revelation.
Compared with every kosher cheddar I've tasted, it is a different food altogether. I would be curious to hear how someone with access to the taste of non-kosher cheddars finds it. But I urge any cheese lovers on this board to send for some. it keeps, or you could slit the shipment with a friend. It is so good, and gives a hint of what we've been missing.
I suppose I could compare it to the moment fresh kosher mozarella first became available. A whole new level of taste.
