Dave Lebovitz offers yet another awesome dessert that is simple to make: The Chocolate Cake Recipe I Found on a Men's Room Wall - David Lebovitz
Now, he just links to the actual recipe, which is in French. I could have guessed at the ingredients, but who wants to screw up a chocolate cake?
I figured, Google has a translator, and also tried babelfish (the first translator I'd ever tried way back when).
They both had pretty poor translations, I could have guessed better. But, if you look now, the Google translation is pretty good (just mussing up the coffee - it's really an espresso, and not a full cup, just an espresso's worth). The Google translator lets you view the original wording by mousing over, and lets you suggest better translations. And, over time the translation of that page gets better. It certainly improved in the last two weeks.
Somebody in the comments provides a nice translation.
I made the cake last night for Mary's birthday, and (this time) I increased the chocolate to 300g, as David Lebovitz suggests. I think I prefer the original ratio. The first time I baked it up, the cake cooked a little more evenly, and the final texture was pretty light. This one was really chocolaty - the center kind of goey. While delicious, I prefer less chocolate. If I were to do the 300g chocolate version, I'd up the baking time to 17 minutes or so, and perhaps reduce the temperature slightly...
Gee, sounds like I have some experimenting to do.
