Make sure you break for at least 3 days after one session of instant noodles before you eat your next packet! Please read the info shared to me by a doctor. My family stopped eating instant noodles more than 5 years ago after hearing about the wax coating the noodles - the wax is not just in the Styrofoam containers but it coats the noodles. This is why the instant noodles do not stick to each other when cooking.
If one were to examine the ordinary Chinese yellow noodles in the market, one will notice that, in their uncooked state the noodles are oily. This layer of oil prevents the noodles from sticking together.
Wanton noodles in their uncooked state have been dusted with flour to prevent them sticking together. When the hawker cooks the noodles, notice he cooks them in hot water and then rinses them in cold water before cooking them in hot water again. This process is repeated several times before the noodles are ready to be served. The cooking and rinsing process prevents noodles from sticking together.
The hawker then 'lowers the noodles in oil and sauce to prevent the noodles from sticking if they are to be served dry.. Cooking instructions for spaghetti require oil or butter to be added in the water when boiling the spaghetti to prevent the pasta from sticking together. Otherwise, one gets a big clump of spaghetti!
