Egg-free version: Squeeze the sweet potato with your hands to release a little juice. If not juicy, add a couple of tablespoons of water. Mix with 2 teaspoons of tapioca/cassava or arrowroot starch, salt and pepper, which will coat the sweet potato with some batter and will help it stick together when cooking.
