I am looking for a recipe called Chocolate Temptation that my mom and grandmother always made . It is sort of like a mousse, but does not use gelatin. It uses egg whites. The other ingredients are dark chocolate baking squares, butter, egg yolks, powdered sugar. when mixed, it is poured into a square pan which bottom is covered with graham cracker crumbs. Then a light sprinkling of the crumbs on top and chill. I don't know the measurements for the ingredients. Does this sound like a familiar recipe to anyone?
