Resurrecting this lovely thread I haven't baked in over 5 years. A sin! My father wanted sourdough quick, so I experimented with Professor Calvel's starter, with some modifications. I only did half the recommended amounts and since I didn't have malt extract available, used malted milk, 2 gr instead of the 1.5 gr it called for. Followed the schedule given for that starter, but the 2nd 7hr feeding wasn't very succesful (suspect my father had too much nicotine on his hands), so I left the starter out without food for 6 more hours, than resumed the schedule once things got bubbly again. A miracle! We got a pretty decent starter after only 3 days (instead of the weeks it took my all natural flour/water). Fed it equal parts in weight of flour and water to try to reach 100% hydration, since the original mixture was way dough-y. Tested the starter with some Sourdough English Muffins and it was ready for use. I followed jackal10's method, converting the amounts to grams, as follows: Prefement: 200 gr sourdough starter 150 gr white all purpose flour (only had regular 10% flour, so that's the one I used) 225 gr water Left for 5 hours on the counter. Dough: 200 gr refreshed sourdough starter 450 gr white all purpose flour (again, regular 10% flour) 225 gr water 9 gr salt (added later) I roughly mixed the ingredients and left for 15 minutes, then came back and kneaded by hand for 5 minutes. Left for amylisation 30 minutes and then added salt. Kneaded for another 10 minutes. Rested the dough for an hour, then gently folded using Dan Lepard's technique. Repeated the folding operation every hour 3 more times. Shaped the dough into a ball and put it in my makeshift banetton (wicker basket covered with cotton cloth, rubbed generously with rice flour). Left the shaped dough 40 minutes at room temperature, then put it in the fridge to retard overnight (11 hours) The next morning I preheated the oven to 250 C for one hour. Put some brick tiles in the middle of the oven and a tray in the bottom. Took the dough out of the fridge and put the dough in the floured peel (rice flour) and slashed it badly. Need more practice in the slashing department: Turned down the heat to 230C and slid the dough into the stones with a little too much force (expected it to stick a bit but it didn't), then fiddled with it to try to put it properly on the stones, elongated the shape doing this Put 3 icecubes in the tray at the bottom and set the timer for 48 minutes. Got a lovely boule with a crisp crust Sliced the bread after a 3 hour wait. Yum! Crumb holes are ok-ish for a 10% protein flour I guess, but I want a better, bigger-hole crumb. Just got my hands on 12% flour, so next time I will be using that. Flavor is really good for a young starter, I expect it to become more complex with time. What other tips and tricks do you recommend? Thanks so much for your feedback!
