This is a Southern adaptation of an Irish favorite. Many substitutions have been made here to the standard recipe (most notably, the absence of cabbage), and many more adaptations are welcome. That’s the nature of this springtime dish. This slow cooker recipe will yield a thin, dark, rich Dr. Pepper broth that will inject all 23 of its hidden flavors into the veggies and meat. The resulting broth is a lot like some of the brown-sugar recipes mentioned elsewhere, but the difference here is that you can substitute the Dr. Pepper out for Ginger Ale (for a tangier flavor), Coca-Cola (for the more conservative chef), Sunkist (soda version of the traditional Orange Juice Corned Beef recipe), or beer (limitless varieties of flavor here).
