French Fridays with Dorie: Michel Rostang’s Double Chocolate Mousse Cake

I have another true confession to make this week: I’m not that into chocolate. When it comes to chocolate, I can take it or leave it. I know some people will find that hard to imagine, but that’s the way it is.

I say this because, for French Fridays with Dorie, the recipe this week was a very chocolately cake: Michel Rostang’s Double Chocolate Mousse Cake. What a decadent cake, with a very fancy name, for an ordinary week! Fortunately, I am married to a chocoholic, who comes from a family of chocoholics so I had an enthusiastic audience.

For chocolate, I used a bar of Ghiradelli’s 60% bittersweet, which, chocoholic or not, I always have on hand. This recipe called for coffee, but I’m not really a coffee drinker. I do like espresso drinks, but I get them for a treat from Starbucks, Peets or my favorite Lexington coffee shop. So, as embarrassing as this is, I made some extra-strong instant coffee to add to the mousse mix.

Firm but still glossy?

The chocolate mixture came together easily, more easily than I expected. The part I was most unsure about was whipping the egg whites. I wasn’t sure exactly what firm but still glossy meant. I’m not sure I did it right, but whatever I did worked out.


I did made a mistake with the springform pan rim. (By the way, the 8-inch springform pan is definitely getting a workout with the dessert recipes in this book.) I couldn’t decide whether to place it right side up or upside down. Because it was just acting as a rim, I was worried the little edge on the bottom would cause a problem later, so I used the rim upside down. Oops! The top edge, which I placed on the parchment, was slightly rounded. When I baked the bottom crust, a little bit oozed out onto the parchment paper and, eventually, burned. It wasn’t pretty, but it wasn’t the end of the world. I think I should have just used it with its usual orientation.

I didn’t plan the timing quite right. I baked the crust after dinner, but there wasn’t time for it to chill before bedtime, so the crust chilled overnight. Dorie said the mousse could be made a few hours ahead, so I worried it might deflate overnight. It survived. The next night I baked the cake with the mousse layer and we ate it warm for dessert. Then, for night #2, we had the baked and chilled version.

Howard, the chocoholic, preferred the warm version. My opinion might not matter as much, given my indifference to chocolate, but I agree with him. This cake was interesting, but so far this month, I’ve only liked, not loved the recipes. I have high hopes for next week’s Chicken B’stilla.
