1. For the clarified milk: In a small saucepan, heat the milk until it’s scalding hot – bubbles will appear around the edges.
2. Mix in the lemon juice, orange juice, and tea. Stir to combine, then cover and refrigerate overnight.
3. For the spice syrup: Bring the sugar, water, and spices to a boil. Let sit overnight, then strain through a double layer of cheesecloth or a coffee filter. The resulting liquid should be completely clear.
4. Mix the clarified milk with the spice syrup and serve over ice with a grating of fresh nutmeg.

Tip: For an alcoholic version, add your choice of liquor (rum or vodka is suggested), as well as a dash of Angostura bitters.
