Apple Crisp drink

My friend, J, from PA, recommended a drink called Apple Crisp. She said it is so yummy for Christmas!

1 oz dark rum (Goslings is good)
1 oz unfiltered apple juice (simply juice brand is nice)
1/2 oz brandy

Mix ingredients together and pour over ice in a rocks glass. Add a generous splash of seltzer on top and then top with cinnamon and sugar (like what you put on cinnamon toast!) A very big hit- your friends would love it and you just might need one after a crazy day with the children. These are strong! She made a batch in a pitcher and her bartender served them all night.
