Help! I made your Flourless Chocolate Cake for Passover Dinner tomorrow and as soon as I took it out of the oven (after 1hr 27min BTW), it fell. I would like to try to make it again, but want to correct whatever mistake I've made. That said, can you give me reasons that it might have fallen? I made sure the egg whites were soft peak and gently folded in egg yolks/sugar combo and chocolate. I suspect it might be the cooking time, but am not sure. I did touch the top of the cake and although it seemed "firm", as specified in the recipe, perhaps it wasn't firm enough.
