If you over cook it, it’ll be soft and no good and it’ll break up when you eat it. You need to cook it at the right amount of time so that it doesn’t break up.
Boil a pot of hot water and wait until it boils. Pour in the noodles and let it cook. Turn it all even. Take it out when it’s about 90% cooked. If it’s soft enough you’ll be OK. Sometimes you will dip it in hot water soup later so it can be 90% done and you’ll be OK. It won’t be over cooked later.
Take the noodle out and wash it in cold water to get rid of the hotness and stickiness and let it dry. Turn it around so that everything can get a chance to dry. Serve when ready.
