Why this matters
Salt strengthens existing flavor, acid adds contrast, fat carries aroma and softens sharpness, and fresh finishes can lighten a rich dish. They are not interchangeable cures. A safe, cooled taste gives you useful information; one small adjustment shows whether your diagnosis was right. That deliberate loop is more reliable than shaking several seasonings into the pot at once.
How to do it
Salt pasta or potato water after it comes to a boil, using the recipe as your guide and accounting for salty sauce ingredients. Stir so the salt dissolves before adding food.
What to look, hear, or feel for
The cooked starch should taste seasoned on its own, not aggressively salty. For pasta, save some water before draining if the sauce may need it.
When something goes wrong
If you forgot, season the finished dish gradually. Do not pour a large amount of salt onto drained pasta where it cannot distribute evenly.
Try it in a real meal
This is especially useful for soups, sauces, grains, vegetables, and rich dishes that can taste heavy even when they contain enough salt.
