A kitchen timer is handy for people like me who look at the clock to time something being cooked/baked and after some time mostly either a) forget to go check on the dish after the prescribed amount of time has elapsed or b) remember all about checking on the dish but totally forget what the start time initially observed was, thus making it difficult to calculate the elapsed time.
