Mulligan stew is a dish akin to Irish stew, Brunswick stew, and burgoo originally prepared by hobos in their camps from meat, potatoes, vegetables, and whatever else could be scrounged. The hobo who put it together was known as the "mulligan mixer". Nowadays, this kitchen sink special is a terrific way to recycle leftovers into something new and delicious. From the Southern chapter of the United States Regional Cookbook, Culinary Arts Institute of Chicago, 1947. Cooking time approximate.
