Chocolate Yogo

Ingredients
40 g cocoa powder
40 g cornflour
120 g sugar
800 mL milk

Method
Sift the dry ingredients together and mix with 300 mL of milk.
Heat the remaining 500 mL of milk in a saucepan until it gets hot.
Pour the chocolate milk into the hot milk and whisk until the mixture thickens.
Remove from heat and pour into a bowl that you can place cling wrap over securely. The plastic wrap must touch the surface of the pudding with no air trapped beneath, otherwise a skin will form.
Place the bowl in the fridge overnight.
