You can also find Maykway curry powder in supermarkets, it's in a small pot - the blue lidded one is the one that tastes most like Chinese chippy curry. Very annoyingly it has no nutritional info, but the main ingredient is wheatflour, the rest of the ingredients are spices which are free.
I syn this as if it were wheatflour and add 6 syns on top as right at the end of the ingredients list it says 'vegetable oil'
I normally make a really really good curry for two out of it and count approximately 12 syns for the whole thing.
