If you rifled through the Campbell’s soup labels I collected as a kid, you’d notice a heavy concentration of Beef and Barley Stew labels. It was my favorite soup. By far. Now, though, I’ve moved so far away from processed foods that it (sadly) just tastes salty and gummy to me. I’ve been meaning to concoct a homemade replacement for years, but somehow have never gotten around to it. Early in the new year, though, I had a pot of beef stock leftover from the holidays, some stew meat and carrots from my CSA, and an expanding enthusiasm for kohlrabi. It was time. If you can’t find kohlrabi, substitute potatoes, or another root vegetable like turnips or rutabaga.
