Add, to a medium bowl, the water, yeast, salt, brown rice syrup and olive oil, and whisk everything together. In another bowl, combine the flours. Add the yeast mixture to the bowl with the flour and knead until you have a firm, yet soft to the touch, dough. If the dough is too wet, add more flour until you reach the right consistency. Cover the bowl with a clean kitchen towel and leave it in a warm place to rise for 2 hours.
