To make chocolate ice blocks that turn out exactly like the expensive store-bought ones, at a significant saving. First make a chocolate custard. Place 500ml milk in a saucepan (I use fresh whole milk, but you can use reconstituted powder milk for extra savings) and bring it to the boil. Then add a tablespoon of sugar, a tablespoon of cocoa, and a tablespoon of cornflour. Stir constantly until thickened, then cool. Second, pour the cooled chocolate custard into pre-moistened ice block moulds. Freeze for at least three hours. Cost to make one ice block (if using powdered milk): approx 6 cents. The cost to make one dozen is approx 80 cents. Savings: $27.60 per dozen (based on the price of a dozen chocolate ice blocks at the corner shop).
