Do you know of a bullet-proof sourdough Ciabatta recipe? All that I've made either didn't rise, or were too weak so they spread out a lot before rising...
Ciabatta is hard. I have tried the recipe (and others) from "the perfect loaf"-- but never exactly because I don't have easy access to the flour brands he uses.
The key thing, IMHO, is high-protein (high gluten) bread flour. It helps to keep structure with any high-hydration dough. Also, if I remember correctly, ciabatta should not proof too long, or it gets too slack. I used a canvas couche and made the loaves relatively small.
