You will find many of the ingredients in local Asian stores. Don’t be put off by names you don’t recognise, like shaoxing or Chinese rice cooking wine; sherry, or any other rice wine, will suffice. If you cannot find potato flour, cornflour is fine (although potato flour will create a
crisper result and when used for thickening the sauce will be richer and clearer). A good wok is a worthwhile investment for quick and efficient cooking of Asian food. The mushroom bowl with pork balls is super-quick. Use fresh noodles, as you can toss them in at the end and cook in just a few minutes. The joy of this dish is that it’s all in one pot, so there is minimal clean-up. Instead of pork you could make it vegetarian, adding tofu at the end as an alternative protein.
