Steam or boil the sweet potatoes until soft.

In a mixing bowl, combine sweet potatoes, vegan butter, hot water, sea salt, black pepper, onion powder, garlic powder, sourdough starter, psyllium husk, arrowroot flour, and baking powder. Mix until well combined.

Divide the dough into equal portions.

Roll each portion into a flat tortilla shape.

Cook each tortilla in a skillet over medium heat for about 3 minutes on each side, or until cooked through.
