I found this video which really shows how mozzarella is made. It’s home-made in this vid, but it shows why the cheese is called ‘mozzarella’ which comes from the word to ‘pull off’.
Also, mozzarella is a cool word to try to pronounce well. There are two Z’s and two L’s so you have to stress them or pronounce them both. Try to say ‘MOZ ZAH reL LA’ These are called ‘doppio’ or doubles in Italian. It’s what makes Italian so languid and beautiful. Try saying pizza as PIZ ZAH – it’s just gorgeous!!!
