THE revival of handmade bread that has, happily, taken hold in many parts of the country means more leftover bread. Just the other day I received in the mail a small softcover book, Cooking With Artisan Bread, by the pioneering and excellent baker Gwenyth Bassetti, one of the founders of the Grand Central bakeries, in Seattle and Portland, and Jean Galton, who writes in her introduction, "Our hope is that this book will spare you the guilt of throwing away another wedge of slightly stale -- but still wonderful -- bread." In Italy the uses for stale bread go far beyond French toast and croutons, and some American chefs are so crazy about the Italian way with old bread that they have taken to increasing their bread orders just to let some go stale.
Their aim, often, is to make panzanella, a homey, refreshing salad that takes advantage of the late-summer bounty of ripe tomatoes and offers all the pleasures of dipping bread into the collected juices at the bottom of the salad bowl. Panzanella is the pizza of Tuscany -- a bread-and-tomato combination known round the world, perhaps because it's an easy one-dish meal. This one requires no cooking and none of the careful presentation that, say, salade niçoise does. (The origin of the lovely name, including its relation to pane, the word for bread, is disputed.) Like pizza, the original version is uncomplicated -- panzanella constants are bread, tomatoes, onions, oil and vinegar, and basil or parsley, with celery and cucumber as near-constants -- and best understood before a cook explores the myriad variations.
Tuscans aren't much good at making pasta, but they did invent the Renaissance. In frugal, blunt Tuscany it's beans or bread. "Tuscans, like Yankees," the Maine native Nancy Harmon Jenkins, who for twenty-five years has had a house in the heart of Tuscany, writes in her new "are thrifty in their approach to food (truth is, one of their favorite foods is leftovers), and they share a similar passion for beans: Other Italians call them mangiafagioli, bean-eaters."
Tuscan bread isn't like any of the sourdough breads currently in fashion here. It's denser and chewier -- and famously saltless, although Jenkins has never found a wholly plausible reason for this (the possibilities include parsimony and tax avoidance). Saltless bread does keep longer; salt attracts moisture, which in turn attracts mold. And bread made with a starter dough, like traditional Tuscan bread and much of the new American sourdough bread, takes longer to get moldy than bread made with packaged yeast. I've never found real Tuscan bread in an American artisan bakery, despite the many good breads I've tasted that go by the name: Americans don't have a taste for saltless bread, let alone the patience for the long, long chew of old Tuscan bread. About the only way you can observe this long life in your own bread box is to bake Tuscan bread, following the directions in Flavors of Tuscany or in Carol Field's ever-reliable Italian Baker.
Traditional Tuscans bake bread only once every ten days. After the fifth day they think about making one of the dishes based on pane raffermo, "firm bread," of which there are, naturally, a lot. One is crostini, slices of bread covered with chicken livers or some other savory spread. Most of the great thick Tuscan soups involve pane raffermo: acquacotta ("cooked water"), a simple vegetable soup served over slices of old bread; ribollita, a cabbage-and-bean soup served both over and under slices of grilled bread that are usually drizzled with olive oil (they are also sometimes sautéed, hashlike, with thick leftover soup); and a warm cousin to panzanella -- pappa al pomodoro, bread simmered to a pap (hence the name) with tomatoes and vegetables.
is very firm. Old Tuscan bread does not shatter at the entry of a knife, as stale bread made with commercial yeast does. Under careful, steady pressure it slices into intact pieces, almost like balsa wood. Tuscans reconstitute old bread by dipping it in water, for panzanella, or broth, for crostini; the slices hold their shape. (So do the bagel-shaped barley rusks called friselle in the southern region of Puglia, which are then topped with, for instance, diced tomato, oregano, oil, salt, and pepper. These come with breakfast at Il Melograno, a hotel I love near Bari.)
Panzanella classically begins with soaking slices of stale bread in water. The liquid makes the salad cool and refreshing, and perfect for a hot summer afternoon: dressed with oil and vinegar, the salad both satisfies hunger and, the way acidic drinks like lemonade do, slakes thirst. The texture of the soaked bread is fluffy -- very much like the cracked wheat in tabbouleh or like couscous, which is not a grain but tiny pasta pellets. Stale American bread is not fluffy when soaked. It quickly turns to mush. Panzanella made with soaked American bread is more like cold pappa al pomodoro.
THE texture problem led me to try a few alterations in the usual method when I set out to make a plausible panzanella with the "rustic Italian" loaves from my local bakery: omitting the bread bath as a matter of course, and sometimes toasting the bread first. I worried, though, that I was straying too far, like most writers of Tuscan cookbooks in English. So I consulted Fabio Picchi, whose restaurant, Cibreo, is the most celebrated in Florence, at least by people searching for genuine Tuscan food made with the best ingredients -- and raw materials are everything in such an unadorned cuisine. The bearded Picchi, whose eyes seem always to be hiding an ironic smile, has the swagger of a turn-of-the-century aristocrat painted by Boldini. He is also something of a kitchen cutup, as I discovered when I assisted him at a dinner he cooked recently at the Four Seasons restaurant, in New York City, to celebrate the publication of a new edition of Faith Heller Willinger's indispensable guidebook For the dinner Picchi lugged many heavy cans of Tuscan tomatoes -- he doesn't trust imports from southerly regions.
