baking with grandma

Last year when I was visiting my grandma, I decided to ask her to teach me how to make her "bing." Little did I know that she doesn't use any standard measuring cups. She uses mugs and tea cups of all different sizes! And when the consistency of the flour wasn't right, she just sprinkled some more. Nevertheless, it was impossible for me to come up with a recipe to duplicate it at home. This was the end result after they were finished baking. The fillings we used were sesame paste and red bean paste.
