The perceived intensity of salty, sweet, and bitter taste qualities is greatest in the 60o
F temperature zone. Consequently, when seasoning a 180o
F preparation that is to be served later at room temperature (72o
F), such as potato salad, use less salt than your taste buds suggest during the hot test sampling. Do the reverse when you salt-test a room temperature food like a leftover soup that you plan to reheat.
