Ok - this is not my recipe. This is pretty much the recipe from the back of plain ol' chocolate bars in France, and honest-to-goodness, it's the one most Parisians use. I swear! It's dead simple to make (the hardest part is remembering to leave the butter out to soften), but it always impresses. My kind of recipe. —erin e k
Melt the chocolate with a spoonful of water. In a pinch (ok, always) I do this in the microwave. Add the butter and mix well.
Separate egg whites from yellows; add yellows one by one to the chocolate, mixing well after each addition.
In a separate bowl, whip egg white with a pinch of salt until stiff peaks form. Add egg whites to the chocolate and fold delicately (delicately!) for a light and airy mousse. Under-mix rather than over-mix.
Chill in the fridge for 2 hours or so and pull out after dinner. Ta-da!
