Deep freeze birthdays
After a week of bitter wind and
bone-freezing chills, Montreal is finally starting to warm up again. I saw the
first signs of life on my Friday commute to work: even though they were bundled
up as ever, people were walking with their heads up, not bent against the
winter gales. There were even a few joggers out! A good sign, no doubt. Ottawa was also stirring from its
frozen slumber when I arrived on Friday night, a great way to start a birthday
weekend with family.
For my mother’s birthday dinner,
we went to Zen Kitchen, an excellent, intimate bistro in downtown Ottawa that
serves gourmet vegan fare with a first-rate wine cellar. Vegan is not often
associated with fine cuisine, but places like Zen prove that, in the hands of a
talented and creative chef, meat and dairy-free ingredients can be turned into
innovative, delectable dishes that are filling without being carb-ladden. So in
anticipation of the night’s meal, my mother and I wanted to make a dessert that
would be simple but luxurious, decadent (vegan-ism not being a requirement). We
settled on a dark chocolate truffle tart with a thick, rich, barely sweet
filling supported by a nutty graham cracker crust. Vanilla whipped mascarpone
finished the dish, adding an airy creaminess to the intense truffle base and
just enough sugar to bring out the sweetness of the graham cracker and to
complement the deepest chocolate flavor.

Ingredients
Graham cracker crust
- 1
cup finely ground graham crackers (I used
a food processor but a Ziploc bag and rolling pin work equally as well)
- 2
tbsp granulated sugar
- 3
tbsp unsalted butter, melted
Truffle filling
- 3/4
lbs (12 oz) good-quality bittersweet chocolate, finely chopped
- 1
cup whole milk
- ¼
cup unsalted butter, cut into 4 pieces
- 1
tsp pure vanilla extract
- ¼
tsp table salt
Vanilla whipped mascarpone
- 1
cup mascarpone cheese, at room temperature
- ¾
cup heavy cream
- ¼
cup granulated sugar
- ½
tsp pure vanilla extract
To make the crust
1. Place
a rack in the centre of the oven and preheat to 350F. Have ready an ungreased
9½-inch fluted tart pan with a removable bottom.
2. In
a medium bowl, mix the cookie crumbs and sugar with a fork until well blended.
Drizzle the melted butter over the crumbs and mix with a fork until crumbs are
evenly moistened.
3. Place
the crumbs in the pan and spread over the bottom and sides of the pan. Use your
fingers to pinch and press some of the crumbs around the inside edge of the pan
to cover the sides evenly and create a wall about a scant ¼-inch thick.
4. Redistribute
the remaining crumbs over the bottom and press firmly to make a compact layer.
5. Bake
the crust until it smells nutty and fragrant (about 10 minutes). Set the baked
crust on a rack and let cool.
To make the filling
1. Melt
the butter, chocolate and milk together in a medium bowl using a double boiler.
Whisk in the vanilla and salt until smooth. Set aside, whisking occasionally,
until room temperature and slightly thickened, about 1 hour (for faster
cooling, place in the refrigerator until thickened to a pudding consistency,
scraping down the sides of the bowl every 5 minutes with a rubber spatula).
2. Using
a rubber spatula, scrape the mixture into the prepared crust, being careful not
to disturb the edges. Let cool completely, cover and refrigerate until set,
about 4 hours.
To make the vanilla whipped
mascarpone
1. In
a medium bowl, combine the mascarpone, cream, sugar and vanilla. Using an
electric mixer, beat on low speed until almost smooth, 30 – 60 seconds.
Increase the speed to medium-high and beat until the mixture is thick and hold
firm peaks, about 1 minute. Do not overbeat.
To assemble: With a rubber
or metal spatula, spread the whipped mascarpone over the set tart. Sprinkle
with cocoa powder and serve with hot espresso (or Irish coffee).
Note: whip the mascarpone just
before serving, or the peaks will deflate slightly (though will taste equally
as good).
