Feed your starter: In the morning around 7 to 8 am, feed your sourdough starter. You want to feed so you have the 130g bubbly starter needed for this recipe, plus an amount remaining to feed for your next loaf.
Mix your dough: Once your starter has doubled in size, is very bubbly and active it is time to mix your dough. Mix the flour and salt. Next add in the water and sourdough starter. Roughly combine with a danish whisk or your hands. Then cover with a damp tea towel, place some place warm and rest for 30 minutes. Stretch and folds: After 30 minutes of rest, perform your first round of stretch and folds. Lift a quarter of the dough up and stretch high above the mixing bowl, then fold it back down over the top of the dough ball. Spin your bowl and repeat with the next quarter of dough. Do this until you have stretched and folded all around your dough.Rest your dough again for 30 minutes. Perform another round of stretch and folds.Do this processs a total of 3 times, over 90 minutes. Proofing: Proof your dough by allowing it to rest in a warm place in your kitchen. Usually for 6 to 8 hours. Keep in mind, this is very temperature dependent. If your kitchen is hot in the middle of summer, your dough may only need 3 to 4 hours. If it is cold, it may take up to 12 hours to proof. Typically comfortable temperature, your dough should be ready by 8 or 9 pm.
Shape your dough: Flour an area of your kitchen benchtop and gently empty your dough out. Gently stretch your dough out to a rectangle.
Bulk ferment: This is when you cover your shaped dough in a plastic bag and rest it in your fridge overnight.
