It is important to note that you can turn the razor clams with a spatula or chopsticks from time to time during the cooking process so that all the razor clams are heated evenly and you can check to see if they are fully cooked. The razor clams are basically ready to be removed when all the shells have opened up inside and the meat has become tender and white. Finally, it is recommended to add a proper amount of salt, minced ginger, garlic and other seasonings to the cooked razor clams to enhance their flavor.
