Most Bulgogi recipes call for crushed pear. This is for tenderizing the meat. My boyfriend’s Korean mother says Coca-Cola® can also be used for the same purpose. This recipe uses very thin-sliced meat so tenderization isn’t necessary. Sugar is used instead.
My boyfriend loves this recipe and even prefers it to the Tuscan soup at a well known restaurant! I adapted this from a diabetic-friendly recipe, if you want to make it that way substitute sweet potato for the yellow potato.
