This is somewhat left-field but I cannot find the answer anywhere else (including ChatGPT!).
Cake decoration relies on piping nozzles. It seems that various manufacturers/retailers have different codes to identify the size and pattern of their products. I would like to see a comprehensive cross reference of manufaturer, pattern, size, etc. A couple of manufacturers, for example Wilton and Cake Decorating Corner, provide a breakdown of their own products but such lists do not translate to other countries (such as the UK where I live) or manufacturers.
Anyone know of such a list/resource for those of use who make cakes and want to decorate them beautifully?
