Korean-style clear beef soup 

I had lots of beef stock leftover from the oxtail soup, so I decided to improvise.  Bring beef stock to a boil, then add daikon radish (cut into thin squares).  Cover and let simmer for about 20 minutes, then add scallions, cut into straws.  Continue to simmer for about 5 minutes, then season to taste.  Here, I added some Korean beef boullion powder (sogogi dashida), a Tbsp of Korean soybean paste (doen jang), and some freshly ground black pepper.  Garnish with minced scallion greens (which adds a fragrant contrast) and serve with short-grain rice.  (Jan. 2013)
