Kosher salt has large, coarse flakes and no additives, while table salt is fine, dense and usually iodized with anti-caking agents. Because kosher flakes are bigger and lighter, a teaspoon of it contains less salt than a teaspoon of table salt, so you cannot swap them one for one by volume.
Kosher salt = coarse, light flakes, no additives. Table salt = fine, dense, iodized. Not a 1 to 1 swap; kosher measures less salt per spoon.
Why They Measure Differently
Table salt’s fine grains pack tightly, so a teaspoon holds a lot of salt. Kosher salt’s large flakes leave air gaps, so the same spoon holds less. As a rough guide, one teaspoon of table salt equals about one and a quarter to two teaspoons of kosher salt, depending on the brand.
Which to Use When
Cooks often prefer kosher salt because its flakes are easy to pinch and sprinkle evenly, and it has no metallic iodine taste. Table salt dissolves fast and suits baking, where precise amounts matter. To be exact across salt types, weigh the salt rather than measuring by spoon. Accurate measuring spoons and a kitchen scale both help.
Kosher vs Table Salt
| Kosher salt | Table salt | |
|---|---|---|
| Grain | Large flakes | Fine grains |
| Additives | None | Iodine, anti-caking |
| Per teaspoon | Less salt | More salt |
| Best for | Seasoning by hand | Baking, precise use |
Frequently Asked Questions
Is kosher salt saltier than table salt?
By weight they are similar, but by volume table salt is saltier because its fine grains pack more tightly into a spoon than kosher flakes.
How do I substitute kosher salt for table salt?
Use more kosher salt by volume, roughly one and a quarter to two teaspoons of kosher for every teaspoon of table salt, and taste as you go.
