I got this recipe from Bon Appetite. It is really a terrific desert and pretty easy. I get tons of compliments every time I make it. If you can't find pre-made creme fraiche at your local grocery store you can make your own the day before (see directions below), ...tons of other creme fraiche recipes on Zaar. Check the tart as it cooks, if the top starts to brown too much, place a tin foil tent over tart. Be careful not to let the foil touch the tart custard, it ruins the look of the baked custard.
