I've got a good custard figured out, 1/2c milk, 1 large egg, 2T sugar and 1/2t vanilla extract. Today, I am trying flavoring it with a bar of Hershey's milk chocolate. I melted the chocolate in warmed milk, then added to the egg beaten in the sugar. Strained everything into a 4 ounce ramekin, I always seem to lose a little of the liquid. Now it's hanging out in a water bath at 350 for 45 minutes. As long as the chocolate doesn't scorch cooking at 350, it should turn out awesome.
