Watching Ming Tsai- he described as a Japanese Rice bread crumb. Having used it for years I always assumed this was the case. When cooking for my grandmother-in-law who has a gluten allergy, I thought this would be the perfect way to prepare numerous dishes that are restricted. I then read the ingredients and it's made from wheat gluten. Has this always been the case? Is there a certian brand that is gluten free, or a similar product that is??
