This is a fusion dish - Chinese, Korean, Moroccan and Italian. Coffee is the hidden binding flavour.
If you cannot find the 3 in 1 instant Asian coffee powder in a packet - the substitute is to mix 1½ tablespoon of instant coffee with 2 teaspoons of sugar and ½ cup of milk. Mix well and omit the ½ cup of water when prepariing the sauce in the wok. The substitue for Korean Hot Sauce is 2 tablespoons of Sweet Paprika mixed with 1 tablespoon of water and 1 chopped deseeded chillie.
