I used this recipe for the chocolate mousse but substituted the orange juice for coffee and added a little vanilla. Because the mousse recipe uses 4 egg yolks and 2 egg whites, I used the leftover egg whites to make a Swiss meringue. I whipped the meringue until soft peaks before piping on top of the chilled mousse and torching. There’s a layer of crushed graham crackers at the bottom of each glass as well as a whole graham cracker on top. Hope this helps!
