Turkey Sausage With Sweet Potato

Precook the sweet potato.
Boil a kettle with hot water. Add cubed sweet potato to a pot with boiling hot water and ½ teaspoon of salt. Cook over medium heat for 10-12 minutes until soft when inserting a knife. Once cooked, strain and set aside to cool. This step can be made ahead of time.
Preheat the oven to 200 C / 400 F.
Make the sausage patties.
Mash enough sweet potato to tightly pack 1 cup or so (you don't need to be super precise here). Add that and all other ingredients (but the flour) to a bowl, and mix together using your hands. Combine until the mixture comes together well. Add the tapioca flour or cassave flour and mix through; this will thicken the batter slightly more.
Line a flat roasting tray with a sheet of baking paper and brush it lightly with some olive oil or coconut oil. Wet your hands and roll the mixture into small patties. Place them evenly on the tray. Keep rinsing your hands in between batches to prevent the mixture from getting sticky. You should yield 12 patties.
Bake the sausage patties.
Place the tray in the oven, middle shelf. Set the timer to 25-30 minutes. There is no need to turn the patties over. They will get more browned on the bottom and golden on the top. Remove and cool off before transferring to a container (if refrigerating for later). Otherwise, enjoy as they are or serve as a side with other foods or a smoothie/juice.
