There are a lot of hot sauces out there, and new ones are hitting shelves regularly. (The popular UK-based Nando's PERi-PERi recently arrived at US grocery stores, for instance.) Unless you're a fiend for burning sensations, it might be hard to know what you're getting into when you grab a bottle of the red stuff. If you only want a little heat, should you go with Frank's or Cholula? If you like a sweetness, do you need Tabasco or Sriracha?
The folks at Sriracha2go.com have attempted to help clear things up. They have created a chart ranking popular hot sauces by their score on the Scoville scale, which ranks spicy food by the amount of heat it's packing.
