I just can't eat that much cheese! I wanted to do cheese of the week but I can't keep up.
This is Queso Quesadilla, a Cacique product . They make a line of Mexican cheeses, cremas and chorizo sausage. Their website has recipes and descriptions of what the differents cheeses are like, which is handy because they look pretty much the same when they are in their little round packages.
This cheese doesn't have a lot of distinctive flavor. But it is very, very smooth and melts like a dream - the perfect quesadilla cheese. It is much much better for quesadillas than monterey, which tends to separate, or stringy old mozzarella.
