Look at the pathetic crust and tasteless, quick-rise bleached flour interior, on this Ace Bakery ciabatta from Loblaws.
If you have no access to indie bakeries such as Jean-Pierre Challet's http://lematinbakery.com , and are stuck with grocery-store bread, get thee to Sobey’s for some Boulart from Québec http://boulart.com . That is all.
