Tart of Prunes

Cook the prunes in wine for about an hour (or until the prunes have plumped and the wine is syrupy). Put prunes though a colander with egg yolks ,to remove skins (it may be necessary to also use cheesecloth to collect all the fruit pulp). Add sugar and pour into pie crust. Bake at 350°F for 45-60 minutes (until pie has thickened in the center).
