Celtic Sea Salt® Fine Ground Celtic® comes from the Light Grey Celtic®, just low temperature dried and crushed for convenience. The mineral profile is retained and the ease of use increased. Fine Ground Celtic® is great for baking and works well for those who are new to natural unrefined salt. Our Fine Ground 8oz Shaker is ideal because it has big holes and a clip-on lid that helps to keep the moisture at bay. It also comes filled and is refillable!
