One reviewer said they add tuna or salmon to make really good fish cakes.

These yummy balls of goodness are inspired by the Austrian and central European knödel dish, which are essentially rounded potato or flour dough balls poached in water or stock and sometimes pan-fried . They are usually served as a side dish with meats and stews. I think I saw some knödel balls in a deli window in Vienna and they had some spinach through it and I thought that’s a great idea to sneak in some green vegetables in a dish.

I used sweet potato and spinach as a base and just a little bit of tapioca flour to help the mix bind together better as there is no egg in this recipe. The mixture will be thick, and although sticky, will roll into balls easily. I called them the bombs because when you bite through a slightly crispy outer layer, the cakes explode in your mouth and their warm, soft gooeyness spreads in your mouth. Yum or what?!? Perfect for active days when you need more carbohydrates than usual.
