Red-Bean Rice & Kimpira Burdock

We go to my grandma's house with my family, brother and sister. My grandma prepares red-bean rice cooked from 3kg of rice! Red-bean rice & kimpira burdock are deli-deli :-) Even something special condiments are not added when I ask the recipe, why my grandma's kimpira is so tasty?!
After lunch, we still keep eating such as ice cream or cake, and I come back home with full stomach. Thank you!
