Story Behind this Recipe
My husband's cannot eat gluten, so we started substituting rice flour for wheat flour, and tapioca powder for katakuriko.
Since this has a lot of yamaimo, it's a soft and creamy okonomiyaki. Be careful when flipping it over! Rather than mixing in the tempura crumbs, you can sprinkle it on top of the batter when cooking for a crispy texture. It has gluten, so if you have allergies just omit it.
