This is very much not the ginger tea at Koshy's, which is steeped. Maybe it would have been more appropriate to call this "ginger chai," but then some might have gotten the impression that it's like a Starbucks Chai Latte, but with more ginger. A more accurate name such as "boiled ginger tea" just sounds nasty to me despite the fact that I boil my tea to death just about every morning these days.
2 small slices fresh ginger
2 teaspoons Assam CTC
1 cup water
1/2 cup milk
3 teaspoons sugar or 2 1/2 teaspoons honey
Combine water, milk, and fresh ginger in a small saucepan and bring to a boil on high heat. When milky water boils it will foam. At this point quickly add tea and remove from heat to prevent it from boiling over. After 40 seconds put saucepan back on heat and boil once more. Immediately strain into a mug. Remove ginger from strainer, rinse off, and plop into mug. Stir in sugar. Drink immediately.
