In a medium bowl, whisk together the almond flour, coconut flour, xanthan gum, and salt
Slowly add the hot water to the dry mixture, stirring until a smooth dough forms. The dough should be soft and pliable, but not too sticky. If the dough is too dry, add a little more water. If it is too sticky, add a little more almond flour
Divide the dough into 8 equal pieces. Roll each piece into a ball, then use a rolling pin to flatten it into a thin, round tortilla shape
Heat a large skillet over medium heat. Place a tortilla in the skillet and cook for 1-2 minutes on each side, or until it is lightly browned and cooked. Repeat with the remaining tortillas
