Use Shanghai noodles or any thick and chewy noodles for this dish. The noodles can be bought fresh or dried.
The meat sauce can be made a few days ahead and kept refrigerated in airtight container before use. It can be quite salty and strongly flavoured so be sure to mix with a generous amount of noodles before eating.
The saltiness of the sauce can be adjusted by reducing or increasing the amount of beanpaste use in making the sauce.
