Chai Tea Concentrate

1 teaspoon ground cardamom
1 teaspoon granulated sugar
1/2 teaspoon cinnamon
1/2 teaspoon cloves
1/2 teaspoon nutmeg
1 (14 ounce) can sweetened condensed milk (If you
    prefer a less sweet tea, use unsweetened condensed
    milk, and add sugar to taste when tea is served.)

Mix the spices and condensed milk thoroughly. Refrigerate at least 24 hours before using, and store in refrigerator.

To use, brew a strong black tea. Stir in 1/2 to 2 heaping teaspoons of Chai concentrate mix per cup of freshly steeped tea.
