Salt the grated sweet potato and massage in the salt, then let it sit for 5 minutes. The sat will draw the water out of the potatoes.
Squeeze the water out the potatoes using your hands, or a clean kitchen towel and place them in a different bowl.
Add the onion, garlic, egg and spices to the egg and mix. Mix in ⅔ cup flour or cornstarch. If the mix is too runny, when you hold it in your hand, add up to ⅓ cup more flour.
Divide the batter into 4 and fry each patty in oil until golden brown on each side. Serve immediately!
