This is my second attempt at ciabatta; I didn’t keep the first recipe 
Wonderful chewy crust.
Recipe from https://www.allrecipes.com/search/results/?wt=Ciabatta&page=2
My changes to the recipe:
I used a bread machine instead of mixer,
a regular baking pan,
Scored it into buns with a bench scraper,
and used a convection oven without a pizza stone. Bread is very forgiving.
