Cook them according to package instructions but reduce cooking time by 2 minutes. I like to add turmeric to the water for colour but you don’t have to. I do not add salt to the water in this case as I wash the noodles later. The noodles should be about 80% cooked and a little firm to the bite. Once boiled, quickly drain the noodles in a colander and rinse them well under cold water. This washes away excess starch that causes noodles to stick together as they cool. Toss the washed noodles in oil so they do not dry out. They will be seasoned in the wok.
