A few weeks ago, I made two tart shells and stocked them in the freezer. I used the first for that lovely lemon tart and I had plans for that second crust and it was for a chocolate tart - a chocolate ganache custard tart, to be exact. This is a recipe I've wanted to try for a while ever since I made my first tart last summer because I simply love all things chocolate. Plus, like the lemon tart, this is another delectable yet simple French dessert we can make and enjoy at home.
I started with that simple, no-roll tart shell. This time, I pressed the dough into a rectangular, 13 3/4 by 4 1/2-inch, tart pan (I knew I'd use that pan one of these days!). When you have the tart shell ready to go, the filling is quite simple, calling for four ingredients.
This is all about the chocolate and there are ten ounces of it in this tart, which can serve 10 people. I used a mix of bittersweet and semisweet chocolate since that's what I had on hand. Instead of heavy cream, I opted for half-and-half to cut down on some of the fat. I think the half-and-half provides enough richness but you can certainly use heavy cream if you want the full on effect. For a chocolate ganache tart, the filling (or ganache=chocolate and cream mixture) would simply be poured into a baked tart shell and then chilled. Some professionals actually use a hot air gun to get rid of air bubbles on top of the ganache once it's been poured into the tart shell. I'm perfectly content with some air bubbles on mine but it does explain those perfectly smooth surfaces.
In this case, we're making a custard tart so we whisk an egg and egg yolk into the ganache (chocolate and half-and-half, in this case), along with a dash of vanilla extract before baking in the oven for about 20 minutes.
What you end up with is an elegant dessert fit for a dinner party. The chocolate custard filling is decadent, delicious, and deep in chocolate flavor, with an added bonus of a buttery, crisp crust. It isn't too sweet, particularly when you use a chocolate with a high cacoa percentage, but it is a luxuriously chocolaty way to end a meal. I really like the idea of a tart like this for a dinner party since it's something you can make earlier in the day and there's something special about a tart, particularly homemade. A group can help polish off this tart, which should be eaten, ideally, the day it's made since the tart shell loses its fresh crispness after refrigeration. The center, though, gets fudgier and stays delicious, in my opinion.
If you are a chocolate-lover, I think you'll enjoy this dessert and appreciate the magic that is chocolate ganache. The filling is like a set pot de crème. It's smooth and almost fudgey in texture. I strongly recommend a scoop of vanilla ice cream to go with a slice of this tart. When the two mix together, the center tastes like molten chocolate cake and you didn't need to bake it at the last minute. If you skip the ice cream, maybe a sprinkle of sea salt over the top would be interesting.
