KitchenTimer is a nice website that lets you create multiple timers to keep track of multiple dishes that you are cooking. You can give name of the dish that you are making, and specify countdown time for that. KitchenTimer will start showing the timer on your screen, and when timer is over it will make a noise.
KitchenTimer lets you add multiple such timers, and you can give different dish name to each timer. For example, you can create a timer for Turkey, and another for Stuffing. Each timer can have a different countdown time. Also check out free wardrobe organizer, and free online stopwatch.
Another great feature of KitchenTimer is that it comes integrated with a search feature to search for recipes. Just type the recipe name, and KitchenTimer will do a Google search for that recipe. Then you can open that recipe on right pane of KitchenTimer. So, you get timers on left side, and recipe on right side.
KitchenTimer is a very easy to use website to create kitchen timers, is completely free, and does not needs any registration.
