James Morton's tips on how to make the perfect sourdough
This is when you pick up Super Sourdough by former Great British Bake Off contestant and NHS doctor James Morton.
Makes two small loaves
Ingredients:
100g rye (or white) sourdough starter (if you don’t have one you’ve made yourself, you can buy them online – just look for a reputable bakery or baker)
400g strong white flour, plus extra for dusting
50g wholemeal flour
330g tepid-warm water
10g table salt
Semolina, for dusting

2. In a large bowl, weigh your flours. Add in your sourdough starter. Mix warm and cool water in a jug to get approximately 25ºC (colder than a swimming pool, warmer than tepid), and pour this in. Mix everything together very roughly until you have a lumpy dough – use a wooden spoon, your hands or a dough hook.
3. Let the dough rest for about 20–30 minutes – this short autolyse will help it come together much better. Ideally, cover the bowl with a damp tea towel or a plate to stop it drying out.
4. Add your salt, and then mix your dough – I’d recommend trying it by hand. The slap and fold method works very well. You want to develop the gluten well here – at least 10 minutes of mixing. Alternatively, you can stretch and fold the dough and then repeat this at least every hour of the prove until it seems strong.

If you aren’t stretching and folding every hour, a single stretch and fold about two hours in would be beneficial for the dough’s strength.
6. Once your dough is looking larger and quite aerated, it’s ready to shape. Don’t worry about pre-shaping. Flour a work surface, and a couche or heavy tea towel at the same time (you can use a square proving basket if you have one). Turn your dough gently out onto the surface – use a dough scraper to cleanly separate it from the side of the bowl so as not to stretch the dough too much. Divide the dough by cutting in half using your dough scraper. Dust your hands lightly in flour to stop them from sticking to it.
7. With floury hands, gently stretch out each dough into a large square. Be careful not to tear it. You want each to be about 20cm (8in) square. Then fold the dough in half so that it makes a rectangle and it has floury sides on the top and bottom. If it has stuck, use your scraper and add more flour. Brush off any excess flour from the top, and fold it in half again, gently pressing and holding to make the surfaces stick together. You’ve now got a lightly shaped, wet, aerated square loaf.
8. Use a scraper, or your hands if it hasn’t stuck, to lift the dough onto your floured couche. You can use anything hefty and square-edged (a book will do) on each side to keep it supported as it proves for one to two more hours. You want it to grow by about half again.

10. Dust a tray or board with semolina when you’re ready to bake, and then dust some more semolina onto your proven dough. Get your hands under your couche and flip the dough onto the tray, keeping all the bubbles inside. Score gently – I like to use one diagonal line. Transfer to the oven and add steam using your chosen method – I’d pour some water into a cast-iron pan that’s sitting in the bottom of the oven, or bake under a lid or cloche. Turn the oven down to 230ºC/210ºC fan/Gas 8. Bake for 20 minutes and then either vent the oven by opening the door and allowing the steam to escape, or remove the lid or cloche, and bake for another 30 minutes, or until a deep golden. Cool for at least 30 minutes before eating.
