Step 1

Preheat the oven to 350F (180C). Note: do not use convection setting for this bread (see post for explanation). Spray or grease a 9x5-inch (22.5x12.5 cm) loaf baking pan (or line with parchment paper to avoid all oils).

Step 2

In a large mixing bowl, whisk the sorghum flour, psyllium husks, baking powder, baking soda and salt until blended.

Step 3

Add the water and vinegar, stirring until combined and no dry ingredients are visible.

Step 4

Transfer the dough to the prepared pan. Smooth the top into an even layer.

Step 5

Using a sharp knife, make a lengthwise slash into the dough (about 1/4-inch deep).

Step 6

Bake in the preheated oven for 90 minutes, or until the surface appears pale golden brown, dry and crusty. Cool in the pan, on a cooling rack, for 15 minutes.

Step 7

Remove the bread from the pan and cool completely on the cooling rack before slicing.
