Talking of Mr Bertinet, just pulled this off t' internet...
Richard Bertinet’s Ciabatta Bread Recipe
Yields: 4 loaves
Ingredients for the Ferment (to be prepared 24 hours in advance):
350g (12 1/2 ounces or 2 2/3 cup) white bread flour
190g (7 fluid ounces) water
2.5g (1/2 teaspoon) fresh yeast
Ingredients for the Bread:
450g ( one pound) Italian bread flour (I used unbleached white)
20g (1/3 ounce) fresh yeast
340g (13 fluid ounces) water
75g (5 tablespoons) olive oil or avocado oil
1 tablespoon fine grain salt
oil for oiling
flour for dusting
Instructions for the Ferment:
Mix all ingredients together in a mixer, or by hand, for about 5 minutes until you have a rough dough
Place in bowl covered loosely with plastic wrap and a lint free dishtowel
Rest in a draft free place 17 – 24 hours
Instructions for the Bread:
Put the flour in a mixing bowl and rub in the yeast with your fingertips as if you were making a crumble
Scoop the ferment into the bowl
Add the water, oil, and salt mixing well until all are combined in the bowl
Transfer to the counter with the help of the rounder end of your scraper and work the dough as demonstrated in the Sweet Dough video, below (on original web site)
Mold dough into a ball; lightly oil a bowl with EVOO or avocado oil and place the dough in the bowl covering with a lint free towel and rest in a warm place for 90 minutes, or until bubbly and light
Flour your work surface generously with white flour or cornmeal; with the help of the rounded end of your scraper, turn the dough out onto the counter in one piece
Flour the top; press the dough lightly and gently dimpling it gently with your fingers and divide it into four equal strips
Fold into three: fold one part of one strip over the middle third of the dough gently pressing to seal; bring the other side back over that middle third gently pressing to seal
Finally, fold in half lengthwise, and seal the edges
Preheat the oven to 475°F with a cookie sheet or upside down jelly roll pan on the rack in the oven to be used to bake the bread on
Place the pieces of dough onto well floured lint free dishtowels; cover and proof for 45 minutes
Flour a wooden peel; picking up one ciabatta at a time, turn it over and stretch it lengthwise a little at the same time and lay it on the peel
Spray the inside off your oven with water (I throw in 4-5 ice cubes) and then quickly slide the ciabatta onto the baking stone or tray
Turn the oven down to 435°F and set the timer for 20 minutes: if you are par-baking your bread, set the timer for 15 minutes, cool loaves completely, wrap well, and freeze (Bake from frozen for 12 minutes at 400°F)
For the Thermomix:
Scale the flour and yeast into the TM bowl, and combine for 10 second at speed 4
Add the ferment; scale in the water, oil, and salt and mix to combine for 30 second at speed 4-5
Knead for 3 minutes and follow the instructions above from #5 on.
Note: Plain ciabatta is as common in Italian supermarkets as white sandwich bread is in the United States. Other ingredients are often baked into ciabatta such as chopped olives or sun-dried tomatoes. Ciabatta is often served with soups and salads and is excellent for sandwiches, grilling, or for dipping into olive oil.
