Peel your sweet potato, and then grate it on a fine grater. These shreds need to be small so this will cook properly.
Transfer all the grated sweet potato to a cheesecloth and wring out as much of the liquid as you can. Hash browns fall apart during cooking if the potatoes have too much liquid. You'd be surprised how much liquid is in a sweet potato! So squeeze hard!
Once the shreds are dry, put them into a medium mixing bowl, add the spices and form your patties. I got about 6 out of mine and they are about 2 inches in diameter.
Place the patties into a skillet with oil and cook on each side until each side is brown.
Transfer to a plate and serve.
