You will have to make sure that the house you buy, or build has got a kitchen with a lot of windows and exhaust otherwise, you may feel choked up while cooking your favorite dish.
You cannot work with an old knife and buying new knives every month is not possible, you must keep a knife sharpener, which can also be used for sharpening other blades at home.
You must keep all sort of nonstick pans and pots, they are more reliable and easier to handle. You will not have to fight tough stains.
Along with non-stick pans, keep a cast iron pan as well. you may think that I have gone crazy, but most of the times when the meat is tough to cook, then you must use these pans because they are better conductors of heat, thus cooking your food faster than non-stick pans.
You must buy, a bottle opener, because even though we do not have those type of bottles now, which were quite difficult to open, but still you may need it someday.
Buy a chopper and food factory, which will include a blender and juicer.
You must have a cleaning box, just like a toolbox, keep detergents, surface cleaners and various sponges in it. keep updating this box, because without having a clean kitchen you can not think of a healthy food.
An oven, a microwave and dish washer, these are now an integral part of every modern kitchen. Make sure that you have got all of them otherwise you will not be able to cook contemporary foods.
