010 BLUE - exclusive blue salt rocks in stylish gift pack BLUE ROCK SALT is the rarest and most exclusive salt. It’s ideal for seafood, salads, French cuisine, and truffles. The taste is initially quite present before it changes and becomes mild with a silky-smooth sweetness. Highly popular with children for some reason! The intriguing blue color occurs during the forming of the salt’s crystalline structure, as intense pressure is exerted on the salt deposits. The individual crystals fracture the light in an unusual way creating an optical illusion that makes the salt appear more or less shimmering blue. SPECIFICATIONS Total salt weight: 140 g / 4.94 oz Gift tube: Ø45x135 mm / Ø1.77x5.31 in Total weight: Approx. 170 g / 6.0 oz
