Step 1

Bring a large pot of hot water to the boil, then boil the longevity noodles as per the directions on the packet – probably around 3-4 minutes; take care not to over-cook them, as they’ll go mushy when you fry them – then drain the noodles and set aside.

Step 2

Dissolve the sugar and salt in a tablespoon of boiling water, then combine with the sauces and sesame oil in a measuring jug.

Step 3

In a large, round-bottomed wok, heat the oil then stir-fry the mushrooms, chives and spring onions for two or three minutes.

Step 4

Transfer the noodles to the wok, along with the sauce mix, distributing evenly across the noodles, then stir-fry gently for a minute or two, just enough to combine everything well and ensure an even colour, taking care not to break the noodles. Add more sesame oil if dry or clumping.

Step 5

Serve immediately, garnishing with additional chives or spring onions/scallions.
