Pour milk and sugar into saucepan and bring to a boil. Add vanilla and rice. Cook for twenty minutes stirring occasionally until milk is absorbed (if the mixture becomes sticky add a bit more milk).

Pour rice custard into four ramekins and with a spoon insert the chocolate bites in the middle of mold under the rice. Leave at room temperature. The chocolate will slowly melt and mix with the custard. Let your guests play with the way they want to eat it: mix the whole thing or start by eating the rice laced with melted chocolate and the chocolate hole separately—a matter of taste and mood and a tough decision.
