I bought a small one first that just did spaghetti lengths, just to try it out, didn't want another kitchen gadget that I was not going to us, but I loved it and used it all the time, so bought a larger one from Amazon.....https://www.amazon.co.uk/gp/product/B0142TK6YO/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1
£14.99 Salter one that does two different sizes of spaghetti shapes and a ribbon shape as well and now cook most of my veg this way.
As for the core in the middle, which is only small the size of a pea, I just chop up and throw it in to the recipe.
I have used it on the usually, Courgettes, carrots, sweet potato, red onion, beetroot. You name it you can probably spiralizer it.
Made potato nests. Favorite recipe at the moment is ..
Mexican baked potato nests. Thai beef Salad another. moroccan turkey burgers.Steamed vegetables with honey.
The ribbon cutter makes lovely baked vegetable crisps.
For puddings, Salted caramel & pear pudding. Asian pear fruit salad.
So so far, its used most days. I have even bought one for my daughter.
