This is the way to make a true Peach Melba – with fresh fruit.
Combine the sugar and water. Bring to the boiling point,stirring constantly. Lower the heat, cover, and boil over medium heat for 7 minutes. Remove from heat and add the vanilla. Drop the peaches into boiling water for 1 or 2 minutes, then peel. Cut into halves, removing the pits. Over medium heat, add two peach halves at once to the syrup, and poach 3 minutes. Remove from the syrup with a slotted spoon and chill. Press the raspberries through a food mill or puree in the blender. Stir in ¼ cup sugar. Chill. Put a serving of ice cream in six glass dessert dishes, place the peaches on top, cut side down. Spoon the puree over the peaches.
