Kosher Salt
What Makes Salt "Kosher"?
Kosher salt gets its name from its role in making meats kosher. The larger, coarser grains are perfect for drawing blood from meat, a requirement in kosher food preparation. The salt itself isn't more kosher than table salt — it's just better at the koshering process.
The coarse, irregular crystals that make it ideal for koshering meat also make it the preferred salt in professional kitchens worldwide. Its texture, lack of additives, and pinchability have made "kosher salt" synonymous with "cooking salt" in America.
Why Chefs Choose Kosher Salt
1. Superior Control
The larger crystals are easy to pinch between fingers, giving chefs tactile control over seasoning. You can feel exactly how much you're adding, unlike fine salt that slips through fingers.
2. Pure Flavor
No iodine or anti-caking agents means clean, pure salt flavor. Table salt's additives can impart a metallic taste, especially noticeable in simple preparations.
3. Visual Feedback
The larger crystals are visible on food surfaces, helping prevent over-salting. You can see where you've seasoned.
4. Slower Dissolution
Doesn't immediately dissolve on contact with moisture, giving time to distribute evenly before dissolving into food.
5. Forgiving Nature
Lower density than table salt means it's harder to over-salt. A "pinch" delivers less sodium than the same pinch of fine salt.

When NOT to Use Kosher Salt
Baking
The coarse grains may not distribute evenly in doughs and batters. Fine salt ensures even distribution. If a baking recipe calls for kosher salt, it's usually dissolved in liquid first.
Table Service
Too coarse for salt shakers. The large crystals don't flow well and can be texturally jarring on finished dishes where fine salt is expected.
Precise Measurements
When recipes give salt measurements by weight (grams), any salt works. But volume measurements with kosher salt vary dramatically by brand.
Storage and Handling
Kosher salt requires no special storage but consider these tips:
- Keep in an open container (salt pig or bowl) near the stove for easy pinching
- Doesn't clump like fine salt due to lack of anti-caking agents
- Infinite shelf life when kept dry
- Transfer to airtight container in very humid climates
- Keep a consistent brand to maintain recipe reliability
The Professional Standard
In professional kitchens, kosher salt (specifically Diamond Crystal) has become the de facto standard because:
- Every cook can grab a consistent "pinch"
- Visible on food during prep
- No flavor interference from additives
- Forgiving if slightly over-used
- Economical for high-volume use
- Versatile across all cooking methods
Common Questions
Is kosher salt healthier?
No. It's the same sodium chloride as table salt. The only health difference is the lack of iodine, which some people need for thyroid health. The absence of additives is a preference, not a health benefit.
Why is it more expensive than table salt?
The coarser crystals require different production methods and you get less salt by weight per package due to lower density. You're paying for the crystal structure, not premium ingredients.
Can I grind kosher salt finer?
Yes, but why? If you need fine salt, buy fine salt. Grinding kosher salt defeats its purpose and you'll lose the tactile benefits that make it valuable.
Bottom Line
Kosher salt is the workhorse of professional and home kitchens for good reasons: pure flavor, excellent texture for pinching, visual feedback, and forgiveness in use. Just remember that brand matters enormously for volume measurements. When precision matters, weigh your salt. When following recipes, check which brand they specify. And despite the name, it's not more kosher than any other pure salt.
