Ingredients (for a 1.3 litre mould):
1 packet (12 g) clear agar-agar powder
150 ml sugar
800 ml water
340 ml evaporated milk
8 tbsp ovaltine (milo or cocoa can be used)
8 Oreo cookies, to be quartered
In a medium-sized pot, add agar-agar powder, sugar and water. Cook over medium heat and stir until sugar is dissolved. Add in evaporated milk. Stir well and bring to a slight boil. Divide mixture into two portions (about 600 ml each) into two saucepans. Add ovaltine to one portion and leave the other portion white. Leave both saucepans over low heat in order that the mixtures do not set.
Rinse mould with cold water. Pour 300 ml (half) ovaltine mixture into mould and allow it to almost set. You may store the mould in the fridge for a few minutes to quicken the process.
Once the ovaltine layer is almost set, pour all white mixture into mould. Add the Oreo cookies on top and push them down a little by using the tip of a teaspoon. All mixture to set again.
Once the white layer is almost set, pour the remaining ovaltine mixture into mould. Leave to set in the fridge.
