Time flies when you are having fun. Well, time also flies when the dining room is full, and there is a line of customers waiting to be seated. With so much going on, one can forget how long the roast has been cooking. The best way to combat this is to use a kitchen timer to keep track for you. There are many different kitchen timer types. The classic dial type can be found in many home kitchens across America. For these, you simply turn the dial a little past the desired time, then back to the countdown time, set it down and wait. Digital models offer more options, such as displaying the time of day, counting down and counting up. Some of the more complex models even allow you to set the time for several different food items at once.
