Place the yuca chunks in a large pot and cover with two inches of water. Bring to a boil and cook until the yuca is fork tender, about 25-30 minutes.
Drain the yuca and cool. Cut the pieces in half and remove the small root that runs down the center.
Using a food processor, grate the yuca. Add to a mixing bowl along with the arrow root powder, herb seasoning, salt, pepper, and garlic powder. Mix well.
Take about a tablespoon of the mixture and form into a ball. Repeat until the mixture is used up.
Heat the duck fat over medium high heat in a small cast iron skillet. Working in batches, fry the yuca tots and each side until golden brown.
Drain on paper towels and enjoy!
