Some of the ingredients in this recipe might be a little harder to find if you do not have an Asian store nearby. Some of the substitutes you could use are:
Galangal – you can use ginger here
Shaoxing rice wine – sherry is a reasonable substitute
Chinese black vinegar – a mild balsamic might be a good substitute here although it is not entirely the same. If you do not have balsamic, try a regular good vinegar
Dried Shiitake mushrooms – these might be hard to find too although the dried mushrooms are quite essential for the taste of the broth. Try another type of dried mushroom you can find
