1. PREHEAT oven to 325°F.
2.Place ramekins or ceramic cups in the roasting pan; set aside. Place chopped GODIVA chocolate in a heat-safe bowl.
3. Heat milk, heavy cream, ¼ cup granulated sugar and lime zest in a medium saucepan over medium heat, stirring frequently just until it reaches a boil; do not scald. Remove from heat and immediately pour over chopped GODIVA chocolate. Let stand about 10 seconds then whisk until smooth and shiny; set aside.
4. Lightly beat yolks, egg, remaining ¼ cup of granulated sugar and vanilla extract in a large glass measuring cup or other heat-safe pitcher until sugar is dissolved.
5. Slowly add about 1/3 of the hot chocolate cream mixture into the eggs, whisking constantly. Gradually add the egg mixture back into the pot with the remaining chocolate cream mixture and whisk until thoroughly blended.
6. Strain mixture into a pitcher, then pour evenly into ramekins. Carefully pour boiling water into roasting pan so that it comes half way up the sides of the ramekins. Bake in a water bath, covered, about 40 to 45 minutes, or until just set. Remove ramekins from the roasting pan and cool on wire rack. When cool enough to handle, refrigerate for at least 2 hours.
