In a 2-cup measuring cup or bowl, combine the water, sugar, and yeast.
Stir to dissolve the sugar (or honey). I use a wire whisk to do this.
Cover the cup with a clean cloth and set it aside until it is nice and bubbly (about 5 minutes).
Using the wire whip attachment (not the dough hook or paddle) and the mixing bowl of your Kitchen Aid stand mixer, combine the flour, xanthan gum, and salt, and mix to combine.
Add the yeast mixture, vinegar, oil, and eggs to the mixing bowl and mix on low to combine.
Scrape down the sides once.
Beat the dough on high for 3 minutes.
Spray a loaf pan with baking spray.
Scrape the dough into the loaf pan and smooth the top.
Set it in a warm, draft-free location to raise about 30-45 minutes, or until the loaf has raised about half again as much as it was. It won't double like regular bread dough. NOTE: Do not cover the bread with a cloth as you would with wheat dough. It will rise and stick to the cloth.
Heat the oven to 375°F.
Spray the top of the loaf with baking spray (optional, to help it brown).
Open the oven and spray the sides and top with water. Close the oven door and wait 2 minutes. (You can skip this if you are using a regular loaf pan, but if you are using a French bread pan, this will help make the bread crusty.)
Place the loaf in the oven on the middle rack.
After 1 minute, open the oven and spray the sides and top of the oven with water again. (Skip this step if using a regular loaf pan.)
Bake the bread for 45-50 minutes (loaf pan) until the bread is starting to brown and sounds hollow when you tap it. If I am using a French bread pan, at 40 minutes, I remove it from the pan and put it back in the oven for 5 minutes to harden the sides a bit.
Take it out of the oven and cool it on a wire rack.
Notes
Note 1: This is a single-rise bread! No kneading.Note 2: For egg-free bread, eliminate the 2 eggs and substitute 2 tablespoons ground flaxseed meal plus 6 tablespoons water.
