Handling Tips: 

Hot dogs can be boiled, broiled, braised, baked, grilled, fried, or steamed in beer or any other liquid.

When cooking hot dogs or sausages, don't puncture them. (Use tongs, not a fork, to handle them.) Puncturing them results in some juices leaking out, and that makes the product tough and dry.
