Pots and pans
Until recently, my kitchen was surpassed with hand-down pots and pans. You really only need a few, though. A well-equipped kitchen has three pots (of different sizes), a porcelain, two baking trays, a large baking pan and three pastries.
If you like baking, you can also add a bread pan, two cakes and a cup-shaped tin to the list.
If you have a large family you may need some of these pots and pans. Don't be afraid to add to your collection as needed, but remember not to store for a wild cooking that never comes.
