rock salt


Rock salt has a grayish cast because it's not as refined as other salts, which means it retains more minerals and harmless impurities. It comes in chunky crystals and is used predominantly as a bed on which to serve baked oysters and clams and to combine with ice to make ice cream in crank-style ice cream makers.
