Preheat oven to 350°C/180°F and line a cookie sheet with baking paper. Fill a medium sauce pan with water and bring into a boil.
In a large bowl, mix the almond flour, tapioca flour, baking powder and salt. Add the cider vinegar, maple syrup and water and mix well to combine. The dough should be a bit sticky so keep a small bowl with water on the side to wet your hands before you work with it.
Devide the dough into 8 portions. Form each portion into a ball and press your finger in the center of it to creat a hole and gently put it in the hot water. Remove as soon as the bagels float with a slotted spoon and place them on the baking sheet.
BAKE FOR 10 MINUTES THEN remove from oven and brush with egg yolk or tea and maple and sprinkle your toppings. Return the bagels to the oven and bake for 25 minutes or until golden brown. Let them rest for 10-15 minutes before you slice them.
