What to look for
Pick one brand and learn its volume-to-weight behavior. Equal teaspoons of two brands can contain very different amounts of salt.
Store it thoughtfully
Keep dry in a covered container near—but safely away from—the stove. Label it clearly so it is not confused with sugar.
How to use it
Season in small stages, stir, and taste when the food is safe. Weigh salt in precision recipes such as bread, brines, and fermentation.
When you need a substitute
Table salt has finer crystals and usually packs more densely by volume. Substitute by weight whenever possible, not spoon for spoon.
A common pitfallFollowing a volume measure written for another salt brand can quietly double the saltiness of a dish.
Substitutions change flavor, texture, and sometimes safety or structure. Check the recipe and product labels, especially for dietary needs.
