Time flies fast when you have fun and sometimes you realize that you forgot the eggs boiling on the cooker or the apples exploded in the oven because you didn't take them out in time. Get yourself a timer or a kitchen clock that reminds you when it's time to turn the fire off or stop the dough from leavening.
You have a lot of options to choose from, with different designs and functions. Mechanical timers having a slightly retro look do not require batteries and have a long service life. You can choose a timer with a magnet to attach to the oven, hob or refrigerator. By contrast, digital timers can usually be programmed up to seconds, in the case of food for which time is vital.
