When I first booked my trip to London last fall, the first reservation I made was at The River Cafe, the storied Italian restaurant founded by Ruth ("Ruthie") Rogers and the late Rose Gray. I needed to try the legendary Chocolate Nemesis Cake (the name itself enthralls, does it not?) for myself, by hell or high water.
To no one's surprise, the entire meal was electric: From the fire-roasted Scottish langoustines to the chargrilled squid topped with chilis, to all of the incredible pastas, there was not a moment our party of four couldn't be found nodding and practically cooing over every dish.

“Rose and I found a version of this cake in a magazine in 1988,” explains Ruthie. “We loved the name, but we didn’t think the recipe was quite right, so we adapted it to include more chocolate and beaten egg yolks. The high quality chocolate gives an intense flavor. It’s the perfect end to an Italian meal.”
