Chocolate Ginger

Rating: ****
Ben's chocolate recipe, from the Ben & Jerry's book, pg. 44
+ 1 tbsp of powdered ginger
Diced some candied ginger (~1/4 c.) to add at end.
Didn't seem at first like it would be enough powdered ginger, but it turned out to be plenty.
Used candied ginger that wasn't coated in sugar already. Diced very tiny. Seemed chewier than I remembered.
Texture was a little grainy. Maybe chocolate + milk phase needed to be heated longer? Or maybe it was how the powdered ginger reacted to it?
(This was Rowyn's birthday ice cream.)
