Abstract

A food preparation device can be used for making up formula milk for a baby. The device includes a water tank in which water may be boiled by operating a boil button. Once the boiled water has cooled down to a temperature below a predetermined temperature, the previously boiled water may be reheated to the predetermined temperature by operating a button. Operating the button causes water in the tank to be reheated to the predetermined temperature and to be discharged to a bottle received in a bottle receiving station. If dehydrated formula milk powder has previously been added to the bottle, once discharge is complete the bottle may be capped with a teat, shaken to mix the powder with the water, and used to feed a baby or toddler.
