Into a saucepan, add the orange juice, the sugar and the cornstarch, mix very well until combined. Turn the heat on medium to low, stir it non-stop until it slightly thickens and turns into a smooth and uniform cream.
Equally split this cream into round pots. We've used a cupcake silicon mold, if you have one, you can use it too.
Cover the desserts with plastic wrap making sure it touches the cream and let them chill in the fridge for 4 hours.
Unmold, cut them in half and coat them in grated coconut.
Serve.
