Combine 130g wheat starch, 130g sweet potato starch, and 4g salt in a mixing bowl and mix well
Pour 400ml of water into a kettle and bring it to a boil
As soon as the water boils, pour into starch mixture and stir quickly. It helps if someone can help you pour the water while you stir. If there is no one to help you, you can do 2 pours within 10 seconds apart so that the water stays very hot. Your mixture should look lumpy and a bit translucent. If it’s runny, then your water wasn’t hot enough and you’ll need to redo it…yikes!
Pour in 2 tsp oil and mix together
Cover with a lid or plate for 5 minutes.
During your wait time, line a steamer with steamer paper or parchment paper with some small holes cut into it
When the 5 minutes is up, touch the dough. If it’s still too hot for your hands to work with, then cover for another few minutes. But you shouldn’t wait for it to get too cool, it’ll be difficult to smooth out after it cools
Add the 30g of cornstarch onto the mixture. Use your hands to incorporate the cornstarch into the dough. When the cornstarch has been incorporated, transfer the dough onto a flat surface
Knead the dough until it’s smooth. It should take approx. 2 minutes. Dough should still be warm, soft, malleable and non-sticky
Form into a ball and cut into 4 portions. Put the other 3 portions back into covered bowl
You can either pull a little bit of dough off and roll it into Silver Needle Noodle shape (approx. 5 cm long with pointed ends). Or you can roll it out, cut them into strips and then roll. The latter method will give you a more uniformed size I find that rolling it with your hand on a flat surface the easiest way
Put each finished noodle on the parchment paper in the steamer. Try not to have them touch. Repeat step 11 and 12 until all the dough is used
Steam on high heat for 6 minutes or until the noodles become a translucent colour If you’ve run out of space in your steamer, you can add a steamer stand in your steamer to make a second level
Let cool for a few minutes
Add 1 tbsp oil into a mixing bowl
Transfer the silver needle noodles from the steamer into the mixing bowl, mixing now and then so that the noodles are coated with oil and don’t stick together
They are now ready to be fried
