Smelly hobbies:

I made this mini grand piano in a scent player, called a Scentisizer. Each key produces a different scent, which is dispersed out the side of the piano.

 

Tasty hobbies:

I like to cook from time to times (well, when I have time, so it's pretty rare). However, I regularly make home made ice cream, because it doesn't take much time and you can eat it anytime.  One of my favorite is the chocolate coffee one. Warning: it's very addictive. My recipe is as follows.

Ingredients: - 500 grams of chocolate (18oz) (with 50 to 65 percent of cacao) - 400 grams of sugar (14oz) - 250 grams of butter (9oz) - 400 ml of cream (14oz) - 14 eggs - 5 full teaspoons of instant coffee

Recipe: Melt the chocolate, the butter and half of the sugar together. Split the yolk from the white of the eggs. Whip the yolks with a quarter of the sugar until it becomes nearly white. Mix it with the chocolate. Whip the white of the egg, but don't make it too hard, just fluffy. Whip the cream. Mix everything together very softly in order to keep it fluffy. Put in the freezer. It will take some hours to freeze, so the taste will be optimum from the next day on.
