Once again, going back to my time Sardinia there was a little shop. Cheeses and salami hung from brown twine looped around hooks attatched to the ceiling. The sun beat into the window causing these to sweat fats that stained the butcher paper below. It was a favorite place of mine to buy "guinea rolls", salami and cheese. None of the stuff was refrigerated. I have read of certain cheese types that are several hundred years old. Why now, does cheese have to be refrigerated? What about fine salami? Why do I have to refrigerate them?
