1. In a small bowl, combine the garlic powder, sugar, turmeric, plain flour, curry powder, paprika, chilli powder and salt.
2. Heat the oil in a small pan over a low heat. Add the chopped garlic and ginger. Stir-fry for 2-3 minutes or until just beginning to brown.
3. Add the bowl of combined ingredients and leave for 30 seconds. Stir-fry for a further 30 seconds. This will become very dry.
4. Add water a little at a time, stirring constantly until well combined. Continue adding water until a thin sauce is created. Bring the mixture to the boil, reduce the heat slightly and simmer for 1-2 minutes, stirring frequently until the sauce reaches its desired consistency.
