The Stand Mixer
You need (or you must) invest in a good-quality stand mixer such as a KitchenAid.
KitchenAid mixers, which set the standard for all other stand mixers, come in several sizes from 5-quart bowl and a power output of 325 watts to commercial one 8-quart and 500 watts
Which one should you buy? Buy the best one you can afford.
Also, whichever model you choose, make sure you like the color, because you will be living with it for a long time.
