The Vapo Valve is designed to click when the food or liquid inside the pan reaches approximately 187°F (86°C). Occasionally, slow clicking begins before the pan has been exposed to heat long enough to reach that level. When that happens, proceed as you would without the premature click. The click should stop as the heat rises. Once the temperature hits approximately 187T (86°C), theVapo Valve" will click again. This time, the click will be more rapid and insistent, and it is time to reduce the heat to low.
