How similar is David's Kosher salt to Morton's or Diamond Crystal?
Claude
The short answer is: David's is most similar to Morton, not Diamond Crystal — but precise data on David's is surprisingly hard to nail down.
Here's the breakdown on what's actually known:
The fundamental difference between the three brands is crystal structure, not chemistry. All three are essentially pure NaCl; the "saltiness per teaspoon" variation is purely a packing density issue.
Morton vs Diamond Crystal — well documented
Morton grains are fairly hard, dense, and uniform, while Diamond Crystal grains are hollow and delicate pyramidal flakes. One teaspoon of Morton contains 4.8 g of salt, while Diamond Crystal has just 2.8 g — so roughly 1 tablespoon of Diamond Crystal equals 1½ heaping teaspoons of Morton.
Morton's crystals are made by crushing salt granules between high-pressure rollers, while Diamond Crystal's pan-evaporation process creates the smaller, hollow pyramidal flakes.
David's — less documented
David's describes itself as "extra coarse white crystalline flakes," mined and packed in the United States. It's a mined (rock) salt rather than an evaporated salt, which puts it in the same production category as Morton. The flake geometry is large and coarse, not the hollow pyramids of Diamond Crystal.
The consensus in culinary forums (though a rigorously measured g/tsp figure isn't widely published) is that David's behaves more like Morton — denser than Diamond Crystal, similar enough that most people treat them as roughly 1:1 substitutes. Some sources note a very slight density difference between Morton and David's, but nothing like the ~70% density gap between Morton and Diamond Crystal.
Practical summary
| Salt | g / tsp (approx) | Crystal type |
|---|---|---|
| Table salt | 6.0 | Fine cubic |
| Morton Kosher | 4.8 | Dense flat flake |
| David's Kosher | ~4.5–5.0 | Coarse crystalline flake |
| Diamond Crystal | 2.8 | Hollow pyramidal flake |
If you're following a recipe that specifies by volume, David's and Morton are close enough to use interchangeably with perhaps a small adjustment, whereas swapping either for Diamond Crystal requires roughly doubling the volume. By weight, of course, they're all the same — 5 g of any of them is 5 g of NaCl.

So, a recipe that calls for ½ tsp of Morton's is asking for about 2.5 g?
Claude
Yes, exactly — 4.8 g/tsp × 0.5 = 2.4 g, so 2.5 g is a perfectly good working figure.
