Chocolate Crepes, Lemon Mousse, and Raspberry Sauce


Everyone loves this dessert. The combination is very interesting, indeed: slightly bitter crepes paired with creamy sour mousse and a punch of sweet and sour sauce. It’s heaven!

We like the crepes to be bitter, but if you prefer a sweeter tone, just add a few more teaspoons of sugar. I tried to use my usual crepe recipe once, and it didn’t work out quite well. So, do make some extra effort to make the crepes specifically for this dessert. The results yield a thinner, softer, wrap-able crepes which don’t lose texture when eaten cold.

For the mousse, it’s best to have Meyer lemons, which are much more juicy and have better aroma. Sometimes we found them sold in Trader Joe’s and Whole Foods. If mayer lemons are not available, standard lemons are fine too.
