Morton kosher salt weighs 241 grams per cup — dramatically denser than Diamond Crystal's 128g despite both being marketed as "kosher salt" — because Morton's manufacturing process produces smaller, flatter, more compact flakes than Diamond Crystal's larger, hollow pyramids, trapping much less air per volume.
That density difference is exactly why the two kosher salt brands aren't interchangeable by volume even though they share a category name — a recipe or chef specifically calibrated to Diamond Crystal's lighter texture will come out noticeably saltier if Morton is swapped in at the same volume without adjustment, since Morton packs closer to twice the salt mass into the same measuring spoon.
Morton kosher salt sits between table salt and Diamond Crystal in density, which makes it a genuinely different substitution case from Diamond Crystal when converting to or from table salt — this site's substitute guidance uses a distinct ratio (roughly 1.25:1 by volume against table salt) specifically because treating all kosher salts as one uniform product is a real, common source of over- or under-salted food.
Morton kosher salt's denser, flatter crystal shape (produced by a different manufacturing process than Diamond Crystal's) gives it a considerably heavier cup weight (241g) than Diamond Crystal's (128g) — this is the single most consequential density gap on this site for anyone following a recipe that names one brand specifically, covered in full in this site's dedicated kosher-salt conversion guide.
Morton's crystal structure, closer to table salt's than Diamond Crystal's is, is exactly why Morton requires a smaller volume adjustment when substituting for table salt than Diamond Crystal does — the two kosher salt brands aren't interchangeable with each other by volume despite sharing the same category name.
Frequently asked questions
Why is Morton kosher salt so much denser than Diamond Crystal?
The two brands use different manufacturing processes that produce differently shaped crystals — Morton's are smaller and flatter, packing more densely with less trapped air, while Diamond Crystal's larger, hollow pyramid flakes trap significantly more air in the same volume.
Can I substitute Morton kosher salt for table salt using the same volume?
Not exactly 1:1 — Morton is somewhat less dense than table salt, so use slightly more Morton by volume (roughly 1.25 times) to match table salt's saltiness, rather than assuming a straight volume swap.
Is it safe to substitute Morton for Diamond Crystal in a recipe that specifies Diamond Crystal?
Not without adjustment — because Morton is nearly twice as dense per volume, using the same amount specified for Diamond Crystal will noticeably over-salt the dish; this site's substitute page covers the specific ratio to convert between the two.
Does Morton kosher salt contain any additives?
Morton kosher salt typically contains a small amount of an anti-caking agent, a real point of difference from Diamond Crystal's additive-free formulation — worth knowing if a recipe or personal preference is specifically avoiding anti-caking agents in salt.
Why does this site treat Diamond Crystal and Morton as separate ingredient entries rather than one "kosher salt" entry?
Because their density difference is large enough (128g vs. 241g per cup) that a single averaged "kosher salt" figure would meaningfully mislead anyone measuring by volume — the brand distinction is a genuine accuracy issue, not a minor technicality.
