If it is freshly made wontons, they can usually be cooked for about 5 minutes after being put into the pot. Generally, when the chaos floats to the surface, it is basically cooked. If you serve it out at this time and add a little coriander or the like, the taste will be particularly good.
If it is frozen Chaos, boil it for about 7-8 minutes. After adding the Chaos, wait for the water to boil again for a minute or two, add some cold water, boil again, and continue to boil for 4-6 minutes. Just fine.
