It doesn't matter if it's the kitchen of an amateur home cook who barely uses the space or that of a professional chef, you'll be hard-pressed to find one that doesn't have a jar of salt somewhere. And that jar will most likely contain table salt, also known as "common salt." This fine-grained variety is super versatile and can be used for both seasoning and cooking just fine. But if you want to get the most out of your cooking, you'll need to expand your salt collection, stat. There are dozens of notable salt varieties; but to start, try adding sea salt and kosher salt to your pantry.

The salt you'll find sitting in those fancy glass shakers at restaurants and cafés is most likely table salt. Odds are good that the one you have in your kitchen right now is this type, too. Table salt is produced by blasting high-pressure water at underground salt deposits to reduce them to brine. It's taken up to the surface by a pipe and into a factory where it's dried. After going through several more processing steps, the results are tiny, dense salt crystals that — under a microscope — look like perfect little cubes.

Sea salt for extra flavor

Sea salt, as its name suggests, comes straight from the ocean. Large puddles of seawater are left to bake in the sun, and once all the water has evaporated, flakes of salt appear at the bottom of these pools, ready for harvesting. Unlike table salt, sea salt doesn't go through a lot of processing steps, so it retains trace minerals like magnesium and calcium. 

Kosher salt for everything

Even though table salt is the most common, if you can only choose one type of salt to stock your pantry with, pick kosher salt. Think of it like a salty Swiss Army knife. Whatever task you have in mind — from cooking and seasoning a dish, to canning, pickling, and curing — kosher salt can handle it.
