I had to google because I was confused by this. I always thought Roquefort and "blue cheese" were the same thing, but apparently Roquefort is blue cheese that is specific to a region in France and made a certain way of Sheep's milk.
That said, while it's not my favorite, I do like Roquefort - but I don't have a discerning enough palate to know anything about it! I voted Balsamic vinaigrette, but if a more specific Jalapeno Ranch had been there, I might have voted for it. Turns out salad dressings are kind of hard to quantify!
