1 | Prepare the soaking syrup: mix 250 ml cold coffee, 100 ml sugar syrup and 2 tablespoons whisky in a bowl. |  |
2 | Prepare the cream by beating 250 ml liquid cream, 250 g Mascarpone, 90 g caster sugar, 10 g vanilla sugar, 1 egg and 3 tablespoons Amaretto together. |  |
3 | Take a little of this cream and mix it with 100 g pistachio powder or paste (this is easier to mix in if it is already in almost liquid form). |  |
4 | Pour this mixture into the rest of the cream... |  |
5 | ...and fold in gently with a soft spatula to make the pistachio cream. |  |
6 | Use a gratin-type dish and arrange the first layer of biscuits in the bottom, after soaking them briefly in the coffee syrup. |  |
7 | Cover with a layer of pistachio cream. |  |
8 | Add a second layer of soaked biscuits. |  |
9 | Then another layer of pistachio cream. |  |
10 | Finish by dusting the top with cocoa powder.
Refrigerate for at least 2 hours. |  |
You will notice, I'm sure, how tiramisu always improves on being kept overight in the fridge.
