1: In a pan pour 250 ml whole milk, 250 ml cream and ½ vanilla pod. Bring to the boil. Remove from heat, cover and leave to stand about 10 minutes.
2: Meanwhile, break 200 g dark chocolate, then with a large broad-bladed knife, chop roughly. The aim is to get chocolate pieces as small as possible so that they melt quickly in hot milk.
10: Prepare Irish coffee mousse: into a gourmet whip pour 50 ml sugar syrup, 50 ml cold coffee, 125 ml liquid cream and 25 ml whisky.
You will note that cream volume = volume of syrup + whisky + coffee.
11: A short time before serving, prepare small pots: half fill with chocolate cream. Add a layer of nuts and candied peel.
12: Fill almost to the top with chocolate cream.
13: And top with a layer of Irish coffee mousse.
14: Serve without waiting, otherwise nuts and grapefruit peel will lose their crunch. Add a stip of candied grapefruit peel, and for example finger biscuits.
Remarks
If you don't have a gourmet whisk, make a classic chantilly cream with double or whipping cream (not pouring cream) that you mix with coffee+whisky+syrup, and then whip as usual. You can also use a simple chantilly. You can replace Whisky by Bailey's, the mousse will be a bit less alcoholic. If you will think that there are not enough photos of preparing mousse, you're right. I have forgot to take them when preparing recipe. I'll do it next time, I promise...
