Your starter needs to be properly awake — bubbly and doubled. See the
[starter planner](/starter), including what to do if it doubles before you're
ready to bake.
Ingredients
350 g Water
100 g Active sourdough starter
500 g Strong bread flour
10 g Salt
You’ll need
Large mixing bowl
Dough whisk or a balloon whisk
Damp tea towel
Banneton, or a bowl lined with a floured tea towel
Dutch oven or lidded casserole dish, or a steam oven
Kitchen scales
Bread lame or a very sharp knife
A few ice cubes, if using a Dutch oven
Method
1. Mix the starter and waterPut the water and starter in your bowl together and whisk until frothy and bubbly. You're spreading the starter evenly through the water so it reaches every part of the dough instead of sitting in lumps.
2. Add the flour, and restTip in the flour and mix with your hands or a dough whisk until there are no dry patches. It will be shaggy, sticky and rough — that's right, so don't keep working it. Sprinkle the salt on top but leave it there for now. Cover with a damp tea towel and rest 30 minutes. This is the autolyse: the flour drinks up the water and gluten starts forming on its own.
3. Work in the saltWet your hands and mix the salt through — stretch, squeeze and fold until you can't feel any grit. The dough will tighten noticeably. Cover and rest another 30 minutes.
4. Folds — stretch, then coilOver the next 2 to 3 hours you'll build the strength that holds the loaf up. Start with stretch and folds: lift the dough from one edge, stretch it upwards, fold it back over itself, then turn the bowl a quarter and repeat until you've been all the way round. That's one round. Do 3 or 4 of them, spaced 30 to 60 minutes apart. Once the dough is smoother and starting to hold its shape, switch to coil folds for the last 2 or 3 rounds: lift the dough from the middle and let it tuck under itself, so it ends up rounded with the seams tightening underneath. Honestly, do them whenever you walk past. It's forgiving.
5. Bulk fermentationNow leave it to rise. You want about a 40% increase in volume — and don't let it go past 50%. Over-fermented dough goes slack and bakes flat, so err on the early side. Look for a smoother, puffier dough with some bubbles showing. Timing swings hugely with kitchen temperature, so use the table below as a guide and trust the dough over the clock.
Timing guide
Aim for 40% bigger, and no more than 50%. Time is only ever a guide —
watch the dough, not the clock.

6. Laminate and shapeTip the dough gently onto the bench. First laminate: stretch it out into a large rectangle, which opens the crumb and lines the gluten up. Then shape straight from that rectangle — fold the left and right sides into the middle so they overlap slightly, then roll it from top to bottom like a sausage, tightening as you go. A few gentle coil folds seal the seams. Now place it into a lightly floured banneton SEAM SIDE DOWN — the seam sits on the bottom of the basket, so it ends up on top when you tip the loaf out to score it.
7. Cold fermentationCover and refrigerate. 24 hours minimum for good flavour, 24 to 72 hours is the sweet spot, and it keeps up to 6 days well covered. Longer means more flavour.
8. Choose your bake methodBoth methods start the same way: keep the banneton in the freezer while the oven preheats, then tip the cold loaf out and score it confidently. One decisive cut is better than several timid ones, and it tells the loaf where to open.
Dutch oven
0. Put the loaf in the freezerWhile the oven preheats, put the covered banneton in the freezer. The colder, firmer dough is much easier to turn out and score.
1. Preheat the potPut your Dutch oven inside, lid on, and preheat to 240°C. Give it a full 30 minutes once up to temperature — you want the cast iron properly loaded with heat, not just the air around it.
2. Score, steam, and coverGet the scored loaf into the screaming-hot Dutch oven, drop 2 or 3 ice cubes down the side (not on the loaf), and get the lid on fast. That burst of steam keeps the crust flexible while the loaf springs up.
3. Bake with the lid onTurn the oven down to 220°C and bake for 30 minutes with the lid on.
4. Lid off, finish and colourTake the lid off, drop to 200°C, and bake another 25 to 30 minutes. Keep an eye on it — ovens run hot and you may need to come down to 180°C. You're after deep colour on the crust and a loaf that's cooked through rather than gummy in the middle. Cool it completely before slicing.
Steam oven
0. Put the loaf in the freezerWhile the oven preheats, put the covered banneton in the freezer. The colder, firmer dough is much easier to turn out and score.
1. Preheat with steam oven settingsPreheat the steam oven to 220°C and keep the banneton in the freezer while it heats. Steam oven programs vary by model, so treat these V-ZUG timings as a tested starting point and adjust for your own oven.
2. Score and bake hotTip the loaf out, score it confidently, and bake at 220°C for 25 to 30 minutes.
3. Drop the temperature and finishDrop the oven to 200°C and bake for another 20 minutes. If the loaf is colouring too quickly, come down to 170°C or 180°C for the final stretch. Cool it completely before slicing.
