Combine the ricotta, sugar and 4 oz coconut flakes and stir well.
Shape small balls out of this mixture. You will get about 36.
Chop the chocolate in pieces and place in a small pan.
Pour some water into a larger pot and place the pan into the pot.
Heat over medium heat until the chocolate melts.
When it is melted, stir in the milk.
Take the truffles and use a spoon to toss them with chocolate.
Spread the remaining quantity of coconut flakes on a plate and use 2 toothpicks to coat the truffles.
Refrigerate for at least one hour before serving.
