Just a quick note for myself on what cake tins I have. Just as I decided to post this so I would be able to find the information again, I remembered that years ago I started to tick off the things on the Good Housekeeping Cookery Book list of basics that I already had. So now I'm off to add this information to there, too.
1 x 25cm round springform
1 x 20cm square
1 x Tupperware flower form 21.5cm x 6.5cm (height)
Edited to add: Ha! I knew I had a citrus zester. Haven't seen it since I moved here so if I haven't found it by next weekend, I'm just going to buy another one. This is something I would get a lot of use out of and I'm sick of using the ordinary grater that I have.
