Wow I've never heard of sweet potato sushi. I'm sure the ginger you add to the sauce makes it spicey, I love when sauces taste like that! This seriously looks like something a chef would make.
Nice instructions. You heat up the sushi to 400 degrees in the oven. Isn't the whole point of sushi to be raw?! lol.
Nonetheless, great photography. You should seriously package these and sell them on Shark Tank or something!
