Mont Blanc: Chestnut, My new favourite ingredient

 As I went to Japan in Autumn, and I had a chance to taste many sweet that made from chestnut and it makes me fall in love with this ingredient again.

And when taking about Chestnut, the first thing that I think about is Mont blanc ^^. I made it before (a long, long time ago), and it's a simple recipe. only meringue, cream and chestnut cream. But now I wanted something more, or to put it right, I wanted to play with it more than before.
So I started imagine! What I wanted it to be, the texture, the taste and the look. I wanted my Mont blanc to be soft, not to sweet and packed with chestnut flavour. Because using commercial chestnut cream can make the finished Mont blanc very, very sweet, I used roasted chestnut (with no sugar added) to add chestnut flavour to my Mont blanc.
The base of the Mont Blanc is roll cake, very soft moist genoise, filled with rum loaded cream ^^ and pieces of roasted chestnut. A piece of meringue adds sweet and nutty taste to the cake, it's very delicious so making a lot of it and eating them on their own is recommended!
Because I want more chestnut flavour but not it texture so I turn roasted chestnut into rum chestnut cream to use it as a filling, but if you don't want to spend time making it, place whole piece of roasted chestnut instead (it will be delicious too).
I know that I pour a lot of rum into everything , haha, and yes, I love it but you can use less (or more, if you think it's not enough, hehe), it's your cake anyway!
Piping the chestnut cream is very tricky, it's my second times -*-, and I think I have to make it more often so I can pipe it more beautiful next time.
