Salt Sodium chloride
Salt early and taste often. Salt added at the end sits on the surface; salt added during cooking works its way in.

In the kitchen
Season in layers
Salt the onions as they soften, the meat as it browns, the liquid as it reduces, the dish before it leaves the pan. Salt added at each stage penetrates what is cooking at that stage. All of it at the end tastes like salt sitting on food.
Salt the water properly
Pasta and vegetable water should taste seasoned, not faintly salty — this is the only chance those ingredients get to be seasoned from inside. Most of it goes down the drain, so it uses less than it looks.
It fixes more than flatness
A pinch of salt suppresses bitterness and lifts perceived sweetness. A dish that tastes bitter, or a fruit that tastes dull, is very often under-salted rather than over-anything.
Beyond the kitchen
PRESERVATION
Salting is among the oldest preservation methods known, drawing water out of food so that bacteria cannot grow. Salt cod, ham, bacon, kimchi, pickles, cheese and soy sauce all exist because of it, and entire regional cuisines are built on the results.
SALARY AND SALT
The connection between salary and salt is real in etymology if murky in detail: the Latin salarium is related to sal, and Roman writers connect it to salt. Whether soldiers were paid in salt itself is disputed; that salt was valuable enough to make the story plausible is not.
TAXES AND REVOLTS
The French gabelle, a salt tax, ran for four centuries and was a genuine grievance of the Revolution. The British salt tax in India prompted Gandhi's Salt March of 1930, one of the defining acts of the independence movement.
INDUSTRIAL USE
Only a small fraction of world salt production is eaten. The overwhelming majority goes to chemical manufacture — chlorine and caustic soda above all — and to de-icing roads, which alone consumes many millions of tonnes each winter.
A longer history
Salt production is documented from at least the sixth millennium BCE, at sites including Poiana Slatinei in Romania and Lake Yuncheng in China. Because it is essential to human life and unevenly distributed geographically, it became one of the first long-distance traded commodities anywhere, and salt roads across Europe, Africa and Asia predate almost every other trade network.
Its strategic value made it a favourite object of taxation and monopoly. China operated a state salt monopoly from the seventh century BCE, at times supplying a large share of imperial revenue. The French gabelle and the British salt tax in India both became symbols of unjust rule, and both provoked serious political consequences.
Cheap industrial production in the nineteenth and twentieth centuries turned salt from a strategic commodity into the least expensive thing in the kitchen. The addition of iodine to table salt, beginning in Switzerland and the United States in the 1920s, is one of the most consequential public health measures ever undertaken and is why iodine deficiency has largely disappeared where it is practised.
