The method of kneading dough with sweet potato powder, leek, pork, sesame oil powder and kway teow powder: put sweet potato powder, boiled water and kway teow into a basin, stir constantly, mix the dough and form a ball.

Stuffing: Cut the washed leek into small pieces, add minced meat and sesame oil and stir well.

Take a small piece of dough and knead it into a ball.

Knead into a bowl and steam in a stuffing steamer for more than 20 minutes. It's done!

Tip ① If you don't add kway teow, you may not become a ball. 2 kway teow should be cooked first. When it is hot, it will be very hot at first. You can use chopsticks to stir. The skin should be thicker, otherwise it is not cooked, and it may steam for too long, which may lead to the discoloration of leeks.
