Salt Explained: Kosher vs Sea Salt vs Table Salt

Are you over-salting your food? Discover why the shape of the salt crystal matters and compare Kosher, Sea, and Table salt.

Salt Type Crystal Size Additives Best Kitchen Use
Table Salt Very fine, dense cubes Iodine & anti-caking agents Baking, boiling pasta/potatoes
Kosher Salt Coarse, irregular flakes None (usually pure NaCl) Everyday cooking, seasoning meat
Flaky Sea Salt Large, pyramid flakes Trace minerals from sea Finishing dishes, garnishing desserts

Not All Salt is Equal

Chemically, almost all culinary salt is simply sodium chloride. The massive difference in how we use them in the kitchen comes down entirely to the size and shape of the crystal. A teaspoon of fine table salt contains twice as much sodium as a teaspoon of flaky kosher salt.

Table Salt: The Dense Standard

Table salt is mined from underground deposits and heavily refined into tiny, uniform cubes. It usually contains added iodine (for thyroid health) and anti-caking agents to prevent clumping. Because the crystals are so small and dense, it dissolves instantly. It is best used for baking (where precise measurements are crucial) or salting pasta water. It is difficult to pinch evenly for seasoning meat.

Kosher Salt: The Chef’s Choice

Kosher salt has larger, coarser, irregular flakes. It gets its name from its use in the koshering process of drawing blood from meat. Chefs love it because the large flakes are easy to pinch, allowing for tactile, precise seasoning. It dissolves relatively quickly but provides a gentle, even spread of flavor without being overwhelmingly salty.

Sea Salt: The Finishing Touch

Sea salt is produced by evaporating seawater. While you can buy fine sea salt, the most prized varieties are flaky finishing salts (like Maldon). These delicate, pyramid-shaped crystals provide a satisfying crunch and a burst of clean, briny flavor. They are expensive and should only be used to finish a dish right before serving—never wasted in pasta water.

FAQ

Can I substitute table salt for kosher salt?
Yes, but DO NOT do a 1:1 swap. Because table salt is denser, use half the amount of table salt if the recipe calls for kosher salt, otherwise your dish will be ruined.
Does sea salt have less sodium?
By weight, all salt has roughly the same amount of sodium. However, because sea salt crystals are larger, a teaspoon of sea salt contains less actual salt than a teaspoon of table salt.
