This is a big ticket item, but worth its weight in gold. It will save so much time when it comes to simple chopping or more advanced preparations like mayonnaise. As with most things, buy quality-- it will last longer, be capable of tougher jobs, and give you less problems. To make the food processor easiest to use, leave it on the counter top instead of storing it in a cabinet.

Not too much romance here, but essential for any functional kitchen. Buy the heaviest pans possible. Also, you should consider buying a non-stick silicon sheet: they make baking very easy!

A dull knife is more dangerous than a sharp one, because you apply to it more pressure and force to cut through foods. It can easily slip out of place as you use it and you can harm yourself. Keep your knives in good working condition by sharpening according to their use and time. There's no specified amount of time, because knives vary as much as their use; although, you can easily determine if they need sharpening by the way they cut/slice foods. If a knife can slice through a tomato and tear the skin, then it needs sharpening. If, on the other hand, the cut is clean and quick without any tears, then it needs not be sharpened.
