Combine the cream and milk in a heavy, 2-quart saucepan over medium heat and bring to a boil. Bring the water in a double boiler to a simmer. Place the chocolate in the top half and stir with a rubber spatula until melted. Whisk the egg yolks into the melted chocolate. Slowly pour the boiling cream mixture into the chocolate, whisking constantly. Bring the mixture to a temperature of 160 degrees. Remove from the heat and transfer to a stainless steel bowl. Cool in an ice bath, stirring constantly with a wire whisk to a temperature of 90 degrees.
Evenly divide the mixture into 8 small pot de creme forms or glass custard cups. Cover each with plastic wrap and refrigerate for 2 to 3 hours to set before serving. Spoon the sauce over the top of each pot de creme and serve with
the Florentines.
