Coarse salt, as the name suggests, has larger, coarse grains than regular table salt. This unique texture not only provides a different mouthfeel, but also lends an interesting visual appeal to dishes. Known for its ability to extract and absorb flavors, coarse salt is often used extensively in marinations or in dry rubs for meats.
The larger granules don't dissolve instantly when used in cooking, therefore they offer a robust burst of flavor when bitten into. This quality along with its natural ability to enhance the flavors of ingredients makes coarse salt an excellent choice for grilling or roasting.
