Place the starter, flour and water into a stand mixer bowl
Stir to combine, cover and set aside for at least 8 hours
For the brown bread flour sourdough: day 2
After completing the float test, add the flour, water and salt to the bowl
Using a dough hook, combine the ingredients
Once a dough has formed , knead for 10 minutes
Cover the bowl with a shower cap and set aside for 6 hours
Every hour during this time stretch and fold the dough
Turn the dough out onto a well floured surface and stretch and fold
Shape into a ball with the seam side down
Flour the top then place it seam side up into a well floured proving basket *
Cover with a shower cap and set aside to prove until it passes the probe test
Preheat the oven to 230° Celsius
Gently, tip the dough out onto a lined baking sheet
Slash and place into the oven and bake for 10 minutes
Reduce the temperature to 200° Celsius and bake for a further 30 minutes
Remove from the oven and place onto a wire rack to cool completely before cutting
Notes
Float test: drop a small amount of the rehydrated starter into a glass of water. If the starter floats, it is ready to use. To stretch and fold the dough, I use a dough cutter and pull the dough in from the 3, 6, 9 and 12 o'clock positions, towards the middle. * At this stage I divided the dough in half and placed half into the fridge to make a second loaf when we had eaten the first. This is why the bread is a bit flat. Probe test: gently poke the dough with your finger - if the indentation springs back within a minute your dough is proved.
