Place water, sugar, vanilla seed and lemon juice in a large saucepan over medium heat.  Let sugar gently dissolve and then raise heat and bring all to a boil.  Let boil for 5 minutes and then reduce to simmer.

Cut peaches in half and remove pit.  Poach the peach halves in the sugar water for 3 minutes on each side.  Remove to a dish with a slotted spoon and remove skin.

Once peaches are cool pour sugar syrup over them and refrigerate.

Using a blender or small processor, place berries, powdered sugar, and lemon juice in and process until thoroughly emulsified.  Pour sauce through strainer to remove seeds and pour into a small bowl.

Place 2 peach halves on each plate over a good scoop of ice cream and drizzle raspberry sauce over all allowing it to puddle onto plate.

BUON MANGIATA!
