A few years ago the proprietor of my favorite Boston gourmet shop came up behind me and put something white into my basket. It was a two-pound bag of salt. "We just got this in from France," he said. "Fleur de sel, like no other salt you've ever tasted. So sweet, so creamy, so good, you won't believe it." His eyes burned with enthusiasm. "Please try it," he said.
I knew fleur de sel from a trip to the rocky Brittany coastline, where workers rake salt from shallow waters in an ancient tradition practiced almost nowhere else. And, I was told, no other salt tasted so rich and fresh. The chef I had come to see, Olivier Roellinger, sprinkles the moist, gray-white crystals on a number of the superb seafood dishes he serves at Les Maisons de Bricourt, his inns and restaurants in the village of Cancale, near Mont-St-Michel.
I had long before left ordinary supermarket salt behind for kosher salt, which has a far gentler flavor with no nasty iodine residue, and whose quantity is much easier to control and judge while cooking. But the fleur de sel—from Guérande, on the Atlantic coast—was a revelation, with distinct mineral tastes and a roundness of flavor I hadn't thought possible from salt. The crystals slightly pricked the tongue and then dissolved, leaving a flavor nearly as sweet as it was salty—a mysterious and marvelous sensation.
I didn't find fleur de sel for sale in this country until the proprietor slipped me that bag. I got an idea of why it had taken so long to reach U.S. shelves when the cashier cheerfully told me what I owed her. "You must have added wrong," I said. "I have only some cheese and the salt." "No," she said. "The salt is sixty-one dollars."
It took me a while to recover. In the meantime, salt became the newest weapon in the ever shifting gourmet-chic wars. Fleur de sel is now an essential prestige ingredient on American menus, dusted over a dish at the very last minute so that the diner will have the pleasure of the slight crackle and then the quick, delicious melting. Books celebrating salt appeared. The best for cooks is Salt & Pepper (1999), by Michele Anna Jordan, unfortunately out of print but easily obtainable. Mark Kurlansky, the author of the entertaining and erudite Cod (1997), has just published a natural companion, Salt: A World History. As happens with so many things in the gourmet world, salt became baroque. I started seeing high-priced little bags of colored salt—a designer aberration that seldom has anything to do with flavor—and, much worse, spiced and flavored salt.
Chic aside, fleur de sel continues to offer a matchless culinary experience. Last August, in Portugal, I discovered an even sweeter, whiter, and not incidentally much less expensive fleur de sel than the one that comes from Brittany. It is harvested by young and idealistic marine biologists whose intention was to produce algae.
The driving force behind Necton, the Portuguese company that harvests the salt, is the very energetic João Navalho, who was born in Mozambique of Portuguese parents and moved to Lisbon as a child. While earning a graduate degree in aquaculture, he and a friend, Vitor Verdelho, won a grant to look for new ways to harness Portugal's natural resources. Bargain-rate planeloads of German and English tourists should not be alone in taking advantage of the Algarve's sun and sea, the graduate students thought. Those vacationers didn't help the environment, and neither did the big hotels and developments built speedily and carelessly to house them.
The students wanted to use new technology to produce large quantities of algae rich in beta-carotene, which is valuable to food manufacturers who want a safe, non-chemical orange dye. In 1994 the pair began looking for a part of the coastline with maximal sunlight and plentiful clean seawater. After several years of searching they found the spot: thirty-seven acres of salt marsh in the protected National Park of Ria Formosa, just a few miles from the Atlantic and very near the tourist centers of Olhão and Faro. In 1997 the two, by then recent graduates, formed Necton. A few grants and their education constituted their capital, and they ran the company on socialist ideals: all workers, whatever their position, would be stockholders and would share profits. Then their plans took an unexpected turn.
For thousands of years salt had been a chief reason that people came to this part of the world. The Egyptians were probably the first to evaporate seawater methodically in order to extract salt, and the Phoenicians probably brought early salt-gathering technology to the Portuguese coast. The presence of Roman ruins in the Algarve suggests that the Romans produced salt there; certainly by the year 1000 the Algarve was sending salt to the rest of Europe, and in the fifteenth and sixteenth centuries salt helped Portugal to consolidate its position as a world power.
But the peoples of Northern and Eastern Europe learned to mine rock salt in caves, and by the mid twentieth century mechanization in the mines and cheap transport made sea salt comparatively expensive. Mechanization arrived for sea salt, too, and after World War II the marenotos, salt gatherers of the Algarve, largely abandoned their work tending man-made salinas (salt pans) to find jobs in factories and cities. Navalho and his co-workers were disturbed to find that small abandoned salt pans on their own and adjoining property had become communal dumping grounds.
