Add the flour into the center of the pan in a pile. Sprinkle the xanthan gum and sea salt across the flour, then make a divot in the center of the flour.
Fill the divot with the sugar and yeast, being very careful that no yeast touches the liquid. This is very important if you want the loaf to rise properly.
Carefully put the pan into your breadmaker and turn on the gluten free setting with a medium crust. This setting takes about 2 ½ hours on my breadmaker.
