Sleek, Sumptuous Chocolate Terrine

But this special dessert, which tastes a lot like a rich, thick pot de crème, is eminently doable in a home kitchen, too, requiring little more than good chocolate, a loaf pan, and time.

Like a meat terrine or pâté, a chocolate terrine is baked and chilled well in advance of serving. Come dessert time, either decorate the entire oblong block or portion it into slices and add a garnish or two—a rosy swirl of raspberry coulis, a spray of mint, or a velvety dusting of cocoa powder—and you’ve got a glamorous treat to impress everyone at the table.

With just a handful of familiar ingredients—chocolate, butter, sugar, eggs, and dairy—each has a significant impact on flavor and texture.

I wanted my terrine to land somewhere between the creamy airiness of a mousse and the rich density of a flourless chocolate cake, with enough depth to satisfy any chocophile.

The primary ingredient here is chocolate—I planned on using a full 16 ounces—so it was crucial to select the right kind(s).

After experimenting with every type of bar from the milkiest milk to the darkest dark, I settled on a 50/50 blend of bittersweet and milk chocolate. Marrying the fruity intensity of the former with the creamy, cocoa-y undertones of the latter created impressive complexity. 

With the chocolate settled, the terrine was a breeze to put together. First, I chopped the chocolate and melted it with 10 tablespoons of butter and a bit of salt. (Lots of butter was vital for creating a soft, satiny texture.)

I then whisked in eggs and just 2 tablespoons of sugar so as not to crowd out the chocolate with excessive sweetness. Since the egg proteins would coagulate during baking, I had to use just the right amount. Fewer than four eggs led to collapse; any more and the dessert was unpalatably stiff and eggy. 

The dairy selection was also important.

Dairy fat is solid at room temperature, so the more of it in the recipe, the firmer the terrine became and vice versa.

Whole milk, at roughly 3 percent fat, made the terrine so unstable that it slumped in the center, whereas a heavy cream (about 40 percent dairy fat) terrine held its sharp edges but tasted cloying. I found a happy medium with half-and-half (about 15 percent dairy fat), which made a confection with a neat, boxy shape and an overall lighter—yet still luxurious—feel. 

I strained the mixture into a parchment-lined loaf pan for easy unmolding, cooked it in a water bath in a 325-degree oven, and then cooled it in the same bath. After it was fully chilled (it can be held in the fridge for up to three days or frozen), I unmolded the chocolate block and sliced it to reveal the lush, glossy interior. 

Gussied up with simple but chic garnishes, the terrine was satiny on the tongue with rich, complex flavor.
