If you are new to baking, etc, I suggest you read a recipe you intend making then look in your cupboards and drawers to see if there are any items you already have that will fit the bill. Going out and buying a whole lot of brand new items would probably be a waste of money. You could find out that you buy items that will be used once then relegated to the back of a cupboard, never to see the light of day again.
