Indeed it is. Pepperoni is a kind of salami which is often made with a mixture of beef and pork. It gets its distinctive red color from the paprika that is added to it. You can thaw frozen pepperoni in your fridge. Other types of dried, unopened, packaged, sliced salamis, or whole salami sausages still in their skins, are safe to store in your pantry. They will last for approximately six weeks. Beyond that time, to prolong its life even further put it in the fridge. If you have a strong-smelling salami, you may prefer to keep it stored outside the refrigerator (so it doesn't contaminate other foods with its smell), loosely covered at room temperature for up to 5 days.
