Cut the peaches into 1/2" thick wedges and toss in the lemon juice. Arrange peach slices, with the skin side up, deeply overlapping and nearly standing upright, in a swirl pattern in the crust. Heat jam over low heat just to melt; strain and spoon over the peaches, making sure all are coated. Serve at once. Pass the whipped cream.
