The perfect Summer dessert is one that requires little effort and delivers a lot of oomph. A pannacotta is a classic that despite much written about its ease always impresses people when done right. This recipe is a play on the joy of layers and depths - a parfait of berry jam and maple vanilla pannacotta topped with preserved berries and fresh blueberries. It is silky and smooth on the tongue, has just enough oomph to make you go all jelly inside and has a sweet finish that leaves you satiated and palate coated.
