Split the vanilla bean lengthwise and scrape out the seeds. 

Add both the seeds and the pod to the simmering water. 

Stir to distribute the vanilla evenly through the spice mixture.

Turn off the heat and then add the black tea bags.

Cover the saucepan and let the mixture steep and cool naturally at room temperature.

Strain the mixture to remove the tea bags, vanilla bean, and whole spices. 

Add the sweetened condensed milk and whisk until the mixture turns creamy.

Pour the tea into a large pitcher and refrigerate until chilled. 

Serve over ice or as it is and enjoy.
