Chocolate Hazelnut Mousse

This lovely recipe is mainly by Tarla Aunty and I did my own little changes because I had liked the light coffee flavor in it when I had it somewhere :)
My cousin, Mohit Gupta was my taster for this recipe & he gave me a Thumbs Up for it :D

Ingredients (serves 4)

For The Hazelnut Praline
1/2 cup coarsely chopped hazelnut
1/4 cup castor sugar

For Mousse
1 cup chopped dark chocolate
1/4 cup milk
3/4 cup chocolate hazelnut spread (nutella) , readily available
1/4 tsp vanilla essence
1 tbsp powdered sugar
1 1/2 cups whipped cream
1/2 tsp instant coffee dissolved in 1 tsp water

Method
For the hazelnut praline
Melt the sugar in non-stick pan on a medium flame till it turns light brown in colour.
Add the hazelnuts and mix well to make a praline.
Pour the prepared mixture on the greased rolling board or butter paper and roll it with greased rolling pin so as to get a thin layer.
Once set, crush the praline coarsely with a rolling pin and keep aside.

For Mousse
Combine the chocolate with milk in a pan and melt it on double boiler.
Add the chocolate hazelnut spread, vanilla essence & coffee and mix well.
Add the sugar and whipped cream and fold gently.

How to proceed
Pour equal quantities of the mixture into 4 individual bowls / glasses and refrigerate for at least 3 to 4 hours or till the mousse sets.
Garnish with prepared hazelnut praline.

Tips
You can make a layer of crushed biscuits (and butter) first and freeze it to set and then pour mousse over it.
Instead of praline you can garnish with whipped cream and a chocolate cigar.
You can mix praline in mousse too.
Instead of hazelnuts, you can use equal proportion of walnuts.
If you are using readymade whipped cream, check if it is already sweet or not.
You can also use milk chocolate instead of dark chocolate.
While making hazelnut praline, do not touch the praline with your hands at any point (till its cold) as it is really hot and can cause serious burns.
You can also melt the chocolate-milk mixture in microwave.
