Table Salt vs. Kosher Salt: Key Differences & When to Use Each
Table salt is refined rock salt with fine grains and anti-caking additives; Kosher salt is flaked, additive-free, and engineered for drawing blood from meat in the koshering process.
Home cooks often panic mid-recipe when the jar says “Kosher” and the shaker says “Table.” They look identical on the tongue, yet one dissolves instantly while the other clings to steak, so grabbing the wrong box can over-salt soup or under-season brisket.
Key Differences
Grain size: Table = tiny cubes, Kosher = larger flakes. Density: 1 tsp table salt ≈ 1.5–2 tsp Diamond Crystal kosher. Additives: Table contains iodine and flow agents; kosher is pure sodium chloride. Dissolution: Table melts fast in liquids; kosher sticks to moist surfaces.
Which One Should You Choose?
Baking or brining—pick table for precise measurements. Grilling, roasting, or finishing—use kosher for controlled pinching and visible seasoning. If a recipe specifies “salt” without a type, assume table; if it lists kosher, convert weight to avoid over-salting.
Examples and Daily Life
Sprinkle kosher on avocado toast for crunch; dissolve table salt in cookie dough for even flavor. Swap them in a 1:1 spoon ratio and your soup could double in salinity—always weigh or convert.
Can I substitute table salt for kosher salt?
Yes, but use 25–50 % less by volume and taste as you go.
Does kosher salt taste less salty?
By weight, no; by volume, yes—larger flakes leave air gaps, so each pinch delivers less sodium.
Is iodized table salt healthier?
If your diet lacks iodine, yes; otherwise, either salt is fine in moderation.
