-- Even though traditionally this soup is made with day-old bread, I have tried it also with fresh, good, hearty ciabatta bread that I dried briefly, by cutting it and leaving out for a couple of hours, and it worked just as well. Actually, this way the bread softens faster in the sauce and the soup cooks quicker. If the crust is soft and not too hard, I usually do not bother removing it.
-- This soup is better when it is made one day ahead and then reheated gently. This traditional Tuscan dish is a beloved supper for very young children and for the elderly in Italy, given its tenderness.
