I am making the tempeh sushi rolls from Veganomicon, and I cannot find anything like "Japanese ground red pepper" anywhere. Not at Whole Foods. Not at a cooking supplies store. Not at an Asian Market. Not online. I kind of figured from the name it was going to be hard to find, but what exactly is this spice? I know it's the spice they use when they're making the spicy rolls at Japanese restaurants. Is it just plain ol' chili powder? Paprika? A mix of both?
I ended up with some Korean chili mix, hopefully that will work. I think I will also try chili powder.
