Add a generous amount of rice flour to a well seasoned banneton. Shake it from the bottom and up on the sides, all the way around the basket. Shake out if there is too much excess.
Lay the doily gently into the banneton and up the sides.
Lay your sourdough bread that has been prepared and ready for the final proofing into the basket.
If there is excess on your doily, fold it up an onto your bread dough. Cover the basket securely with Press N Seal. (Follow your directions for final proofing). I put mine in the refrigerator for a minimum of 10 hours.
When ready to bake, prepare your oven and dutch oven per your sourdough recipe. I preheat my dutch oven and oven to 475° for 45 minutes.
When oven is ready. Take the dutch oven out and place on top of oven. Place your parchment paper on your board or counter, turn your dough onto the paper. Gently lift the doily from the dough. Score the dough with your lame. Shallow cuts on the perimeter and a bit deeper cuts on the interior of the pattern.
Take the lid of the dutch oven off and place the paper with dough into it. I put one or two ice cubes between the paper and the pot. Cover and put back into oven and bake for 45 minutes (or per your own instructions)
When your bread is done, take out of the pot and let cool on a rack for one hour. Then it's ready to enjoy!
