Mochi with Chestnuts Filling and Chocolate Topping

I was not careful when I bought this (Refer to http://theunwrittendeed.blogspot.com/2009/08/tcc-prices-are-subjected-to-government.html). I thought it was mochi with chocolate filling and was surprised when I opened the packet. The mochi was yellowish and there was a pack of chocolate powder to sprinkle on top of the mochi. It was nice though, both with and without the chocolate topping. I personally prefer it unsprinkled, since the chocolate taste tends to mask the flavor of the chestnut filling.
