3 tablespoons (26 g) all purpose gluten free flour (I used Better Batter)
1/2 cup (4 fluid ounces) water
3 cups (420 g) all purpose gluten free flour (I used Better Batter), plus more for sprinkling
1 1/2 teaspoons xanthan gum (omit if your blend already contains it)
1/4 teaspoon cream of tartar
1/4 cup (50 g) granulated sugar
2 1/2 teaspoons (8 g) instant (or rapid-rise or breadmaker) yeast
1/2 teaspoon kosher salt
1 teaspoon apple cider vinegar
1 egg (50 g, weighed out of shell), at room temperature
1 1/4 cups (10 fluid ounces) warm milk (about 100°F)
4 tablespoons (56 g) unsalted butter, melted and cooled
Water roux, at room temperature
Melted butter, for brushing (optional)
First, make the water roux. In a small saucepan, place the roux ingredients and whisk to combine well. Cook the roux over medium-high heat, whisking constantly, until thickened enough that the whisk leaves a visible trail. Remove it from the heat immediately and allow to cool to at least warm room temperature. The roux can be made ahead of time and stored in a sealed container in the refrigerator. Just allow it to come to room temperature before baking with it.
Grease and line a standard 9-inch x 5-inch loaf pan and set it aside. In the bowl of a stand mixer fitted with the paddle attachment, place 3 cups of the flour, xanthan gum, cream of tartar, sugar and yeast, and whisk with a separate handheld whisk to combine well. Add the kosher salt, and whisk once again to combine. Add the vinegar, egg, milk, butter, and water roux, and mix well on low speed. Once the dry ingredients have been incorporated into the wet ingredients, turn the mixer up to high speed and allow to mix for about 3 minutes. The dough should be shaggy and tacky to the touch.
Turn the dough out onto a very lightly floured surface, and divide into 3 equal portions (each about 350 grams). Working with one piece at a time, pat out the dough into a flat disk about 3/4-inch thick. Fold the disk loosely in half from one short end to the other. Stack the folded pieces of dough one behind the other, the rounded (folded) part facing up. The shaped pieces of dough should fit snugly in the pan from end to end, and will rise up, not out. Spray the dough lightly with warm water, and cover the pan loosely with plastic wrap. Place in a warm, draft-free location to rise until it has reached about 150% of its original volume. While the dough is rising, preheat your oven to 350°F.
Once the dough has finished rising, remove the plastic wrap, brush lightly with the optional melted butter, and place in the center of the preheated oven. Bake for 45 minutes. Remove the bread from the loaf pan and transfer to a rimmed baking sheet. Return the bread on the baking sheet to the oven and continue to bake until the loaf sounds hollow when thumped on the side and reads about 190°F when an instant-read thermometer is inserted in the center of the loaf and is lightly golden brown all over (about another 10 minutes). Remove from the oven and transfer to a wire rack to cool completely before slicing and serving.
