If I could only have one cheese it would be an old 10-12 X NYS cheddar cheese at Thanksgiving and Christmas.
The rest of the year I try to limit the amount of cheese that I eat, try being the key word, LOL!!!
One nice thing I've found at the local Wegman's cheese counter is a little basket of 2 or 3 ounce tasters chunks of very nice and often expensive cheeses. It allows me to sample some interesting cheeses, the small pieces mask the true cost of the cheese and don't do too much damage to my diet.
