A twist on the classic. Since I have a gigantic bottle of coffee extract I have been looking up recipes involving coffee. And nothing screams classic coffee dessert like a tiramisu. It is also a good way to use up the big canister of mascarpone in my refrigerator.
Makes 8 petit gâteau
For the joconde biscuit sponge
90g icing sugar
60g ground almonds

3) Fold the mascarpone into the pastry cream.
4) Whip cold heavy cream together with icing sugar until soft peaks formed and then fold this into the pastry cream.
5) Pour 23g of diplomat cream into each cavity of the Silikomart stone mold. Soak a joconde disc with coffee syrup and push it onto the diplomat cream.

There will be some leftover diplomat cream.

3) Dip the frozen cake into gourmand glaze and allow the extra glaze to drop off.
4) Spread a small round of coffee caramel on a baked pâte sucrée beurrée disc then place the glazed cake onto the coffee caramel.
5) Decorate with a sliver of gold leaf and allow to set in the refrigerator.
If I make this again, I might make a few tweaks to the recipe. For one, maybe add some Kahlua to the soaking syrup, to amp up the coffee taste. And for another, reduce the gelatine for the diplomat cream as I found it a bit too “set”. The gourmand glaze is delicious though so that is definitely going into my repertoire. Although, full disclosure, I used vegetable oil to make up for the missing cocoa butter as I did not have enough cocoa butter at home. I will be sure to have the right amount of cocoa butter before attempting this again.
