Masala Chai is tea prepared with a blend of spices. This recipe, which I got from Saveur Magazine, is a shortcut worth trying.
1⁄2 cup evaporated milk
4 cups water
5 tsp. sugar
6 black tea bags
5 pods green cardamom, crushed
1. Bring milk, sugar, tea, cardamom, and 4 cups water to a boil in a 2-qt. saucepan. Remove from heat; let steep for 5 minutes. Strain and serve hot.
