Table Salt
Table salt's hub page is unusual among this site's ingredient pages in one specific way: it has a real conversion figure (288g per cup) and real substitution guidance (the kosher salt conversion ratios), but no storage entry at all — because salt, as a mineral rather than a plant or animal product, doesn't have a meaningful freshness or spoilage window the way nearly everything else on this site does.
What makes table salt genuinely worth its own hub page despite that simplicity is the substitution side: its density (288g/cup) is dramatically higher than either major US kosher salt brand, and getting that conversion direction right — using MORE kosher salt by volume to match table salt's saltiness, not less — is one of the more consequential, easy-to-get-backwards conversions on the entire site.
This is a good example of how this site's three facets don't always all apply equally to every ingredient — table salt is a strong candidate for the Substitutes and Convert pages specifically, while its Storage page simply doesn't exist, because there's no real duration to report for an ingredient that doesn't meaningfully expire.
Table salt's small, uniform, tightly-packed crystals give it the heaviest density of any common salt, which is exactly why swapping it for a coarser kosher salt at equal volume goes badly wrong in either direction — see this site's dedicated kosher-vs-table-salt conversion guide for the specific ratios.
Most table salt also contains added iodine and anti-caking agents, both generally absent from kosher salt — the iodine addition, mandated in the early 20th century in the US, was a genuine public-health measure addressing widespread iodine-deficiency goiter, not an incidental ingredient.
Table salt is the most widely owned salt in a typical US household pantry, which is part of why it's the reasonable default assumption in a recipe that simply says "salt" without specifying a type — professional and chef-authored recipes, by contrast, increasingly default to kosher salt instead.
Frequently asked questions
Why doesn't table salt have a storage/shelf-life page like most ingredients on this site?
Because salt is a mineral, not a plant or animal product with organic material to break down — it doesn't have a meaningful spoilage or freshness window, so there's no real storage duration to report the way there is for something like flour or dairy.
What's the most important thing to know about substituting table salt for kosher salt?
The direction of the ratio matters — you need MORE kosher salt by volume than table salt to reach the same saltiness (roughly double, for Diamond Crystal specifically), not less, since kosher salt's larger flakes contain less actual salt per cup.
Does iodized vs. non-iodized table salt change any of this site's figures?
No — the iodine fortification present in most US table salt is too small a quantity to meaningfully affect either the conversion figure or the substitution ratios.
Why does this hub page exist if table salt has no storage page?
Because the hub still ties together the two facets that ARE genuinely relevant — conversion and substitution — even without a storage facet; not every ingredient needs all three to have a useful hub page.
Is pickling salt the same as table salt for conversion purposes?
Very close — pickling salt is essentially table salt without the anti-caking agent or iodine, sharing a similar fine crystal structure and therefore a similar weight per cup.
Is there a reason this page emphasizes the kosher-salt comparison over other salt questions?
Because it's the single most common, most consequential conversion mistake connected to table salt — a household regularly switching between salt types is far more likely to run into the kosher-salt ratio question than any other salt-related conversion.
