Toppings:
Grate Yamato yam in a bowl and mix Kombu Dashi powder. Add shredded cabbage, chopped green onions, and Beni Shoga, then mix well until the cabbage gets wilted. Heat cooking oil in a frying pan. Spread the batter in a circular shape, cover, and cook on low for about 5 minutes. Then flip it over, cover, and cook the other side for 5 minutes until golden brown. Serve on a plate, and sprinkle with toppings.
You can also use Nagaimo (Chinese yam) or regular potato. However, they may be a bit soggy that you may want to add 1 or 2 tbsp. of dairy-free flour.
