Preheat the oven to 190°C. Stir the milk powder and flour together in a medium saucepan. Whisk in the low-fat milk. Bring to a simmer over a medium heat. Add the red capsicum, chilli powder, sugar and cumin, then cook, stirring constantly, for 5 minutes or until thick enough to coat the back of a spoon.
Beat the egg with the egg white in a small bowl. Whisk in a ladleful of the hot sauce. Remove the pan of sauce from the heat and stir in the egg mixture, then stir in two-thirds of the corn and the spring onions. Purée the remaining corn in a food processor. Stir into the mixture.
Transfer to a shallow baking dish set in a roasting tin. Pour hot water into the tin to come halfway up the sides of the baking dish. Bake for 35–45 minutes or until set and the top is light golden brown.
