I always love a good plate of stir-fried shredded potato whenever I visit a restaurant in China, back then before I had the chance to visit China, I never knew potato can be made in such way, still maintaining its crunchiness even after having them blanched and stir-fried. I learnt the secret to making them crunchy during my stay as a consultant in Guangzhou, China. Here I am sharing the secret to make a good stir-fry shredded potato!

Stir-Fried Shredded Potatoes

Crunchy Potatoes Without Deep Frying, How?

Well, potato contains starch, starch is the component that makes them become soft after we cook them. So we will need to remove the starch from the potato, leaving only fiber in a potato and this makes them crunchy. Luckily, this is not rocket science food where you some technical equipment to make. You will simply need a bowl of water to soak the shredded potatoes to allow the starch to be released into the water.
