Put all of the ingredients except the peaches and raspberries into a large pot.
Add the peaches to the pot and bring the mixture to a boil.
Cover the pot with parchment paper and a lid. Reduce the heat to a simmer. Cook the peaches in the poaching liquid for 7-10 minutes, depending on their size. Check for doneness with the tip of a knife. They should be tender but not mushy.
Take the peaches out of the cooking liquid and place them in a bowl. Add half of the raspberries to the cooked peaches.
Add the remaining raspberries to the pot and bring the mixture back to a boil. Reduce the cooking liquid to about half. This takes approximately 10 minutes.
Strain the poaching liquid.
Pour the glorious poaching liquid over the peaches and raspberries in the bowl and serve as desired.
