Ciabatta adapted from The Crepes of Wrath.
It will be a very wet dough - see the step-by-step photos above for more help while making it. If possible, do weigh the flour - it is much more accurate than using cup measures.
Whisk together the flour, yeast, salt and sugar in the bowl of a stand mixer. Add the lukewarm water and knead with the dough hook for 8-10 minutes. If making by hand, use a large spoon and stir vigorously. The dough will seem very wet and sticky, and should stick to the bottom and sides of the bowl - if it seems TOO wet, add a couple of tablespoons more flour (I have to do this occasionally - it seems to depend on the humidity and brand of flour!)
