Spicy Beef Broth Soup with Edamame and Rice Noodles

Just improvised this for my afternoon lunch, and it turned out to be so delicious I just had to share!  This recipe came about because I was trying to think of a use for the 1/4 cup of braising liquid plus beef tallow I had left over from a recent pot roast.  The simplicity of the dish belies the rich flavor it held.  I suspect that its depth of flavor derives from the use of the tallow and braising liquid.  However, since there were no particularly discernible flavors from the original roast, I suspect that any sort of leftover fat and/or enriched liquid will work.

• 2 1/2 oz. rice noodles
• 1/2 cup frozen shelled edamame
• Half a medium onion, finely diced
• 1 Tbsp tallow
• 1/4 cup beef braising liquid
• 2 1/2 cups water
• 2 tsp beef bouillon paste
• 1 tsp oyster sauce
• 1 tsp chili sauce
• 1 tsp brown rice vinegar
• 1 tsp rice wine

Sauté the onion in the tallow.  When the onion is translucent, add the braising liquid and water and bring to a boil.  Dissolve the bouillon paste in the boiling liquid.  Reduce the heat to a simmer and add the oyster sauce, chili sauce, rice vinegar and rice wine.  Taste the mixture to make sure it is properly balanced.  It's ok if it's on the salty side, because the edamame and rice noodles will cut the saltiness.  Add the frozen edamame and let the liquid return to a simmer.  Add the rice noodles and continue simmering until they just cooked through.
