| With updated instructions |
It's been two and a half months since my original post. During this time I've kept mucking (enhancing) with the recipe (my Chemistry/Software/Engineering background - don't know when it's good enough to stop) The core instructions are still from SeriousEats' Kenji; the interpretations are updated. Here's the final product (look! it has horns!)

| Original instructions |
During this
quarantine time, I found this to be a soul satisfying undertaking. Fun with chemistry!😉
You will need: bread flour (preferable), salt, water. For the starter, you can use a mixture of different flours. I found that
raw rye flour gives the best rise, it also darkens the bread a little. I’ve
been staying with unbleached bread flour to continue feeding the starter.
It takes
patience; start with growing the sourdough starter, using the instructions from
SeriousEats. https://slice.seriouseats.com/2010/11/how-to-make-sourdough-starter-day-0.html
Starter
is ready after close to 7 days, when it has lots of bubbles at the top and on the side.
Comments: Make
sure the starter in the container is not concave, (center is lower than side) -
that means the microbes in the starter has depleted their food. Feed it some
more before using it.
Use a scale,
weigh out:
100 gm starter
50 gm flour
25 gm water
100 gm starter
50 gm flour
25 gm water
- OR - if you prefer English:
4 oz starter (consistency like cake batter)
2 oz bread flour
1 oz water
NOTE: the metric measures give a total weight of 175 gm autolysed flour, which is a hair less than the 180 gm that the recipe calls for, but will suffice. The English measures give a total weight of 7 oz, or 198 gm autolysed flour, which is slightly more than the 180 gm called for, so adjust accordingly.1 oz water
Mix well,
cover, and refrigerate for 6 hours to overnight to autolyse.
When ready, it does not need to be doubled. It is now half the volume as shown in photo from my previous post.

Mix
together:
435 grams bread flour,
6 grams salt
Stir so the salt
isn’t sitting at one spot,
180 grams autolysed starter from previous step
300 grams water
Stir well.
Dough will be wet. Let it rest for about 10 minutes.

| Dough mixed, and before stretch and fold |
Stretch and fold about 12 times, or until the dough is smoother (doesn’t have to be perfectly smooth and silky). Instead of using my hand, I have been using the spatula, but the technique is the same. Try not to add more flour. More flour = small holes in the final product.
Move the dough into a bigger bowl for it to rise.

| After stretch and fold (in 95 oz bowl) |
Cover loosely and stick it in the fridge for 3 days per Kenji.
Remove it from the fridge. Let it rest 5-10 minutes or immediately if you can handle the cold dough.
Jelly Rolling shows how to generate good surface tension to avoid pancake bread. I believe the cold dough prevents it from getting sticky. If you repeat the jelly-rolling, it gets stickier, either because the dough has warmed up, but more probably because the gluten structure of the dough is affected adversely. By about the third time, it gets way too sticky (ask me how I know that!) By doing the jelly roll just once,it leads to large holes in the bread. See Wild Crumb vs Even Crumb by Joy Ride Coffee on Youtube.
Load the dough into the boule. Cover loosely and stick it into the fridge overnight. The loose covering dries out the dough a bit and also allows for cleaner slashing before baking.
When ready to bake, put a cast iron pot with top or Dutch oven in the oven
and set the oven temperature to 450 to 475 degrees F. Allow it to heat for 20-30
minutes after oven temperature is reached. (Note: I forgot to load the pot into the oven while preheating, and remedied that by heating the pot and lid(if possible) on the stove top to get it up to temperature)
Remove the dough from the refrigerator. It will have risen about 30%, i.e. not doubled in volume. It is easier to score because it has dried up a bit in the fridge. Score at an angle of 30 degrees and about 1/2 inch deep to generate "horns" after baking. Score the
dough assertively. Because it looked dry when scoring I spritzed it with water (about 12 inches above and across the scored dough, not directly onto the dough itself), don't know if it is necessary, but it didn't hurt the final product.
Lift the
parchment paper carefully to remove the dough from the boule, and put it into the (screaming hot!) cast iron pot cover. If you're using a Dutch oven, put it into the pot itself. Handle it gently (and don't burn yourself) so as not to deflate the loaf. Cover and
bake for 30 minutes, uncover and bake for 25-30 minutes, until the top is very dark.
When 25-30
minutes are up, turn off oven. Let the bread cool before cutting.

| Look at them holes! |

| Original |
Allow it to
cool if you can restrain yourself. Crust should be crackly. The perfect loaf
should have larger holes in the center, smaller around the sides, and “horns”
where the top has been scored. I haven’t achieved the holes and the horns yet –
still trying GOT IT!! See perfect
loaf as described in SeriousEats.
Comment: If you want to keep the starter going,
add 100 grams flour and 100 grams water, stir and let it sit at room
temperature to start over again. Otherwise cover and put it in the fridge, it will keep until
you take it out, and feed it for the next loaf.
After a while
your starter jar will be overflowing if you didn’t discard part of the starter. Pour out all but ½
cup of the starter and start building it up again (100 grams flour, 100 grams water). For the discard, I pour it into
an oiled pan, and fry it up to make a savory pancake, adding green onions,
salt, pepper and whatever herbs available at hand.
