IMO, nothing compares to Danish Blue. I prefer my own taste tests.
I find many of the best brands at Sam's. Their cryovaced beef is excellant. We buy entire strip loins or top sirloins and cut them ourselves as we prefer. We also buy entire cold smoked salmon at $14/lb. It is excellant. They carry very good brands of wine and liquor, often in presentation bottles. Sam's makes volume purchases of the very same goods of the very same quality in the very same packaging available in many other shops and it is this volume purchase and the warehouse merchandising that determines the price.
I can find the same Danish Blue in small quantities at one of the area supermarkets, but at Sam's, I can get a full pound at a much better price per ounce.
From a May 06 review on Danish Blue cheese as compared to Gorgonzola, Stilton, and Roquefort
"Danish Blue cheese is for folks who don't like blue cheese. Not that it is bad or anything, it just fails to impress. Not as tangy. Not as moldy. Not as earthy. Not as creamy."
I have some Danish blue in my refrigerator as we speak. It was on sale. I do enjoy it but I agree with the comparison as I have tasted those also. Other than the American grade cheeses you spoke of, have you compared Danish Blue to the three mentioned?
