Salami vs. Pepperoni

What's the difference between salami and pepperoni? That's easy- salami is for sandwiches, along with cheese and mustard, on rye bread. Pepperoni is for pizzas. Although my dad used to put salami and cheese on a single slice of bread, top it with ketchup, salt, and pepper and put it in the toaster oven. He called it "pizza toast." The only pizza I'd ever had at that time came from a Chef Boyardee kit, so I accepted it. 

But in the real world, salami and pepperoni are both spicy sausages, but that's where the resemblance ends. One has a history that goes back to the Roman Empire, while the other is an 20th century American invention! They are made differently, have different ingredients, and have their own best uses, as I have explained above. The YouTube channel Simple Things - Surprising Histories explains it all, plus an important tip for ordering a pizza in Italy. (via Laughing Squid)
