Long I was undecided whether I need this additional set. Am now but glad it bought to have. Just when I wanted onions finely chopped, they were in the mixer usually porridge, with the fine grater of the basic sets also because it hardly came out of the housing. The middle grater they remained too rough. Since there was only the hand, which was very tearful, especially for larger amounts onions. The onions are now rubbed with Julienne grater exactly as intended. To cut julienne, as initially hoped because of the name, it is not really suitable, since the case is too narrow. These grater I gladly for fresh vegetables, if I want to have it grated fine.
The fine grater is ideal for Parmesan cheese. Bought fresh and rubbed it ... the full flavor! The rest kept airtight, it remains long very fragrant.
Very rarely do I use the Crown Grater. For raw food, fine hash browns or grossly grated Parmesan cheese, but I can also take the rubbing from the basic set.
Really additionally needed, I have this rubbing on the fine Parmesan and onions in bulk. In these cases, I am really happy and do not want to miss it. But for everything else goes well, the basic set with me.
