Mix flour with 2 tablespoons of water to form a slurry, set aside.
Pour oil into a dry sauce or frying pan and place over medium heat.
When hot, add onions and fry until softened.
Add carrot, potatoes, peas, green pepper, red pepper and garlic. Stirfry for one minute.
Add seasoning cube, curry, thyme, dry chilli powder, stir around and add water.
Cook until potato and carrot have softened but not mushy.
Add cabbage and spring onions, cook to soften the cabbage a little then add sweet corn and raisins. The filling should have reduced considerably by now, getting almost dry.
Stir the flour slurry, pour about one tablespoon into the filling and stir.
Cook until it is well thickened. Taste and add salt. If it is not thick enough, stir in more flour slurry.
Take off the heat and spread it out on a plate to completely cool down.
