When salt goes in depends on the ingredient and the cooking method. Salting vegetables early can change moisture and texture, while a soup or sauce can become saltier as water evaporates. Cornell food-science lecturer Chris Loss describes timing as dish-specific; for example, salting mushrooms too early may work against browning. Popular Science interview

A practical tasting sequence

  • Start with part of the recipe’s salt rather than adding everything at once. The goal differs for meat seasoning, pasta water, and a simmering soup, so do not apply one percentage to all of them.
  • Taste a spoonful after it has cooled briefly. If the dish will reduce further, wait before making the final adjustment.
  • Add a small amount, mix thoroughly, and taste again. Acidity, spices, and stock concentration also affect balance; salt is not the only adjustment.
  • For browned vegetables, avoid crowding the pan and choose the salting time based on the texture you want and the moisture released.

Example: If mushrooms are steaming in a crowded pan, adding more salt will not fix the browning problem. Cook them in batches; once the surface browns, adjust salt gradually. For a soup that will reduce, taste again near the end.

Green et al. tested 35 adults with aqueous sucrose, sodium chloride, citric acid, and quinine, alone and in mixtures, using a sip-and-spit rating procedure. Under those conditions, sucrose sweetness tended to be less suppressed than other tastes. This was a sensory experiment at selected solution concentrations, not evidence that adding acid universally makes food taste saltier or a recipe ratio. The authors caution against generalizing to actual foods, other concentrations, or other stimulation methods.
