What to use instead of salt
Quick answer
The closest option is Salt, rated good. The same compound at a different crystal size, and identical by weight. By volume it is not close: flaked salt is far less dense, so a teaspoon of it holds substantially less salt than a teaspoon of fine. Substituting spoon for spoon in the fine-to-flaked direction underseasons; the reverse direction oversalts, and that one is the dangerous half.
It will not do for: Substitution by volume, in either direction; Baking and brining, where fine salt dissolves and flakes are simply slower for no benefit; Anywhere the recipe gives salt in spoons and does not say which salt it means.

Salt
Good matchThe same compound at a different crystal size, and identical by weight.

| Flavour | Aroma | Colour | Heat |
|---|---|---|---|
| very close | very close | very close | n/a |
Works for
- Any application, when measured by weight
- Finishing, where the flake is the point and fine salt would disappear
Does not work for
- Substitution by volume, in either direction
- Baking and brining, where fine salt dissolves and flakes are simply slower for no benefit
- Anywhere the recipe gives salt in spoons and does not say which salt it means
This is the substitution people make daily without noticing they have made one. The honest instruction is to weigh salt anywhere the quantity matters, which is why serious baking recipes give it in grams.
MSG
SituationalReplaces part of what salt does and none of the rest. MSG makes a dish taste more savoury and carries about twelve per cent sodium by weight against salt's thirty-nine, so swapping some of the salt for it genuinely lowers sodium while keeping the dish tasting seasoned. What it cannot do is the rest of salt's work: it does not suppress bitterness, does not sharpen acidity or sweetness, and does nothing physical at all. A dish seasoned with MSG alone tastes savoury and oddly flat.
| Flavour | Aroma | Colour | Heat |
|---|---|---|---|
| partial | very close | very close | n/a |
Works for
- Replacing part of the salt in soups, stocks, braises and savoury sauces
- Dishes already savoury in character, where the umami direction is welcome
Does not work for
- Replacing salt entirely — the result is savoury and flat, and no quantity fixes it
- Baking, brining, curing, pickling and any other job where salt is doing physical work rather than seasoning
- Sweet applications, and anywhere the dish should not read as savoury
No ratio, and the omission is deliberate. Published part-substitution figures exist and they are formulation guidance for manufacturers rather than cooking advice, and the sodium question belongs to a clinician rather than to a spice reference. SpiceHQ holds no clinical source on dietary sodium and gives no dietary guidance here.
Black salt
PoorSalt with a strong egg smell attached. Black salt is sodium chloride fired until part of its sulphate becomes sulphide, so it seasons exactly as salt does and brings an unmistakable sulphurous aroma with it. In a dish that can take that — chaat, raita, a fruit salad — it is an improvement rather than a substitute. Anywhere else it is conspicuous.
| Flavour | Aroma | Colour | Heat |
|---|---|---|---|
| partial | different | close | n/a |
Works for
- South Asian dishes where the aroma belongs — chaat, raita, buttermilk, spiced fruit
- Plant-based cooking wanting an egg note
Does not work for
- Baking, and any sweet application
- Western savoury cooking, where the sulphur reads as spoilage rather than seasoning
- Anywhere the dish should taste seasoned rather than flavoured
Weight for weight it seasons like salt, so this is a flavour decision rather than a quantity one.
