Cooking by the book
When fung shui principles relating to the kitchen were conceived, they obviously could not take into account modern innovations.
The traditional stove had to be kept clean and operational at all times, as it was believed to be where one's wealth was generated. To prevent that wealth from escaping, a solid wall behind the stove in a modern kitchen is preferable. If your stove has a mirror or shiny reflective tiles behind it, then a degree of instability is introduced, which may translate to financial and health problems. Similar problems will occur if your stove has a window behind it that allows you to enjoy spectacular views when cooking; in these circumstances, consider reorienting the stove or blocking part of the view to simulate a solid wall when you are cooking.
Island stoves - those in the centre of a kitchen - lack backing. Consider placing something solid - such as a rack or a stack of cooking books - behind such a structure to provide some support for the stove.
Open-plan kitchens are not considered ideal in traditional fung shui as they do not allow energy to accumulate in the preparation area.
Remember, a clear view of the outside world normally means trouble.
