There are several areas where boundaries apply: 1  Material boundaries determine whether you give or lend things, such as your money, car, clothes, books, food, or toothbrush. 2  Physical boundaries pertain to your personal space, privacy, and body. 3  Mental boundaries apply to your thoughts, values, and opinions.
Scalding is a technique used in many recipes containing milk. To scald milk, you use a heavy bottomed pan or double boiler and bring the temperature of the milk to 85-100Â°C (185-212Â°F). At sea level, the milk should just start showing small bubbles and releasing steam at the lower end of this temperature range.
If it's cold, it's below your body temperature. If it's hot, then it's right around your body's temperature of 98.6Â°F. If the cup is too hot to hold, then you've overheated your milk and the foam won't stay. America's Test Kitchen recommends a minute in the microwave to heat milk to its right temperature.
