Winter Pimms Warm Cocktail from Windsor, England

We were in England last December and had an amazing time. I posted stories and photos on the Blog when we returned. I didn't come back with any recipes but we loved all of the food that we experienced.
We spent time in three places, Birmingham (for the Frankfurt Christmas Market) , London, and Windsor.
We had amazing Indian Cuisine in Birmingham, French Cuisine in London and traditional British Cuisine in Windsor.
We were in a restaurant in Windsor late one evening after walking around in the bitter cold. The restaurant was across the road from Windsor Castle.
The first item we asked for was a recommendation for a warm drink to take away the chill.
The server asked if we had ever had a warm Pimms Cocktail. We had never had Pimms.
We were very willing to try it, and very pleased that we did. It was the perfect warm, British cocktail!

The down side to this story is that I can't seem to find Winter Pimms #3 where we live.
I'm still in search of it so we can enjoy and remember our fond experience in Windsor.

Winter Pimms Warm Cocktail:

5 oz. Pimms #3
14 oz, Apple Juice
1 Apple,  cut into small chunks
1/2 Orange, cut into chunks
1 Cinnamon Stick

Add all ingredients to a saucepan and simmer.
Remove the Cinnamon and serve warm.

Enjoy!
Peace in the Kitchen!
