Sardinian Sale Marino Sea Salt - Fine
500 grams (1.1 pounds) - Sardinia
This currently my favorite size salt crystals. Small crystals come out of my shaker, and it is super quick to salt a lot of surface area quickly. Though it is super easy to over-salt, so I am learning to be careful and keep my overzealous behavior in check.
Fine is good for shakers. Good when you need a lot of saltiness. Good for baking if you need a crystal to dissolve quickly. Good for popcorn.
Just remember the finer the grind the saltier it can be for the same volume.
