To recap: I had one cup of sweet chestnut puree, one cup of chocolate sauce, and about two cups of whipped cream, all told. I mixed the puree and sauce together and folded in a cup of the whipped cream. I chilled it for a few hours and then served it mit schlag.
Oh my god, it was so incredibly rich that I couldn't even finish it. I had to return it to the fridge and eat it later on when I was ready again. With more whipped cream. I will probably never make this ever again, but dang was it sooo good.
