What’s in a Name?

Commonplace in the Wild West, a star fire is a technique in which at least three logs are arranged in a star-shape in a shallow ditch and carefully fed into the fire. For a hotter fire, push the ends of the logs further in towards the center. To save fuel, pull the logs out so only the ends burn at a slower rate. Either way, impress your friends at your next campout by making a star fire to cook up that one-pot cowboy gumbo you've been bragging about all year.
