A kitchen timer is a device used to measure and keep track of time while cooking or baking. It helps ensure that food is cooked for the right amount of time, preventing overcooking or burning. Kitchen timers can be mechanical or digital, and many modern versions come with features like multiple timers, alarms, and countdown displays. These timers are often portable and can be placed on a countertop or attached to a refrigerator. Some kitchen timers are even integrated into appliances like microwaves or ovens. Using a kitchen timer can improve cooking efficiency and enhance the overall culinary experience.
