"Have the 2 teaspoons toasted sesame oil, 1 teaspoon soy sauce, and 1 teaspoon sugar already mixed before you make the noodles. After boiling and draining the noodles, add in the mixture. The sesame oil will prevent clumping. If there is still sticking, add more sesame oil or a neutral tasting oil."
