Activate the Yeast: In a small bowl, combine the warm water, honey, and yeast. Let it sit for about 5-10 minutes until it becomes frothy.
Mix Wet Ingredients: In a large mixing bowl, whisk together the eggs (reserve one for the egg wash), olive oil, and apple cider vinegar.
Combine Dry Ingredients: In a separate bowl, mix the gluten-free flour blend, almond flour, tapioca starch, and salt.
Form the Dough: Gradually add the dry ingredients to the wet ingredients, mixing continuously. If using a stand mixer, use the paddle attachment and mix on medium speed until a sticky dough forms. Add the yeast mixture and continue to mix until well combined.
2. First Rise
Let the Dough Rise: Transfer the dough to a lightly oiled bowl, cover with a clean kitchen towel, and let it rise in a warm place for about 1 hour, or until it has doubled in size.
3. Shape the Challah
Divide the Dough: Once the dough has risen, punch it down to release the air. Turn it out onto a floured surface and divide it into three equal portions.
Roll the Dough: Roll each portion into a long rope, about 12-15 inches in length.
Braid the Challah: Place the three ropes side by side on a parchment-lined baking sheet. Pinch the top ends together and braid the ropes, then pinch the bottom ends to seal.
4. Second Rise
Let the Dough Rise Again: Cover the braided dough with a kitchen towel and let it rise for another 30-45 minutes until puffy.
5. Bake the Challah
Preheat the Oven: Preheat your oven to 350°F (175°C).
Apply the Egg Wash: Beat the reserved egg and use a pastry brush to lightly brush the top of the challah with the egg wash.
Bake the Challah: Bake for 25-30 minutes, or until the bread is golden brown and sounds hollow when tapped on the bottom.
Cool the Bread: Transfer the challah to a wire rack to cool completely before slicing.
Tips and Variations
Flavor Variations: Add raisins, dried cranberries, or chocolate chips to the dough for a sweet variation.
Sesame or Poppy Seeds: Sprinkle sesame seeds or poppy seeds on top after applying the egg wash for added texture and flavor.
Herbs and Spices: Incorporate fresh herbs like rosemary or thyme into the dough for a savory twist.
