My favorite lemon tart recipe is this one from Epicurious.com: http://www.epicurious.com/recipes/food/views/Lemon-Tart-231349. I have made it many times now and can attest it is smackelicious! Making the sabayon may seem intimidating but it is really easy, just takes some patience (and faith) waiting for it to thickened up. I highly recommend some berries on top (blueberries are best, raspberries are good too) and and oh, a side of homemade whipped cream won't be awful either. Bon Appétit!
