Jack and Jill's Iced Jasmine Tea

Bring 10 cups water to a boil in a large saucepan. Place tea bags in a large heatproof container. Add boiling water, and steep for 3 minutes. Remove tea bags. Let cool completely.

Meanwhile, bring sugar and remaining 1/2 cup water to a boil in a small saucepan, stirring, until sugar dissolves. Let cool completely.

Stir together tea and 3/4 cup simple syrup, plus more if needed, depending on desired sweetness. Refrigerate for at least 1 hour. Divide among ice-filled glasses.
