Step 1

Boil water in a kettle and let it sit for 5 minutes. You'll be using 160 ml

Step 2

Add the slightly cooled water to the barley flour and mix well

Step 3

Set aside until cooled. Check temperature is less than 30°C (86°F) before using.

Step 4

Add the white flour to a bowl. Add the scalded barley flour breaking up into small pieces. Add the starter and 480 ml water. This should be about 22°C (71°F). Mix together and leave for 3 hours at room temperature.

Step 5

Add the salt to the autolysed mixture and mix well. Using a stand mixer, knead until the dough reaches between 24° and 26°C (75° to 78°F). Start on a low speed for about 5 minutes, then increase speed to medium. The dough should come away from the sides cleanly. Check that the dough is elastic by pulling a lump gradually apart. Checking the dough temperature is very important. This will set you up for successful dough.

Step 6

Alternatively, knead for 10 to 15 minutes until smooth and the dough is stretchy. The dough should ideally be between 24° and 26°C (75° to 78°F)

Step 7

Move the dough to a large plastic box and leave it to prove for 3 hours at room temperature.

Step 8

During the first proving, fold the dough twice. Imagine that the dough in the bowl has four equal sides. Using our dough scraper, pull up each side in turn and fold towards the middle.

Step 9

After 3 hours place the dough in the fridge overnight.

Step 10

Divide the dough into two equal portions and shape gently into a round. Leave 10 minutes. If you are only able to bake one loaf at a time, put one portion back into the box in the fridge. Then shape that one hour before your first loaf comes out of the oven.

Step 11

Pre-heat your oven to 230°C (445°F) placing your cast iron pans in the oven. Do this at least 1/2 hour before you intend to bake. If you are using a Rofco oven, pre-heating will take 1.5 hours.

Step 12

Shape your loaves a second time and either place them on a couche or in banettons for one hour. If your pan is circular, shape into rounds; if you pan is rectangular shape into oblongs

Step 13

Cut two strips of parchment paper as wide as the loaf and twice as long. You will put your dough on the parchment and place in the cast iron pan.

Step 14

After one hour, transfer the dough to the parchment paper. If you are using a banetton, place the parchment on top of the dough, then a cutting board and then invert it. If you are using a couche, use the pleat to tip your dough onto the cutting board then invert it onto the parchment.

Step 15

Using a lame or sharp knife, score the loaf horizontally. with a shallow cut on one side half way between the top of the loaf and the bottom.

Step 16

Remove the pan from the oven and remove the lid. Put the loaf into the pan and close the lid immediately.

Step 17

Place in the oven and bake for 25 minutes. Then remove the lid and bake for a further 10 minutes. Finally, bake the loaf for 5 minutes out of the pan. Let it cool before eating.
