This is my take on a French classic and is my wife's favourite request. It's not for the faint-hearted and should most certainly not be eaten if you haven't had your gallstones out yet. Or if you have no simvastatin handy. It is extremely rich, but extremely delicious and one for when you're not on a slimming diet. Very simple and quick to make.
This dish serves well with cheesy potato dauphinoise if you really want to be reckless; otherwise a nice tagliatelle and some steamed, slightly crunchy French green beans works very well. A decent Sancerre and Josh Groban in the background will finish the job. Apologies for the lack of photo until I make it next. I guess you could try all the usual creme-fraiche related tricks to reduce calories but I wouldn't bother, just have it once or twice a year and forget about the diet for an evening.
