If your idea of salt is limited to what comes in a shaker, a trip to the West Village will rock your world. The Meadow, which just opened Wednesday on 523 Hudson Street, sells over 100 kinds of salt, from coarse to flaky, volcanic to rose-colored, Mesquite smoked to salt mixed with truffles. Some taste strongly of mineral, others taste fresh from the sea. Shop owner and cookbook author Mark Bitterman wants you to toss your box of iodized salt. "Our focus is on finishing salts," Bitterman told the News. "We suggest using more complex salts at the end of the cooking process rather than adding in the middle." Each salt can be paired with a certain foods. He recommends a flake salt for salad dressings. The silvery-gray sel gris is ideal for finishing meats. A Fleur du Sel makes butter pop. Taster size salt bottles (1.2 oz) start at around $4 and go up from there. Two and half pounds of their multipurpose sel gris will run you about $14.
