1 gallon water
3 (3 ounce) gallon-size tea bags
1 cup fresh raspberries
1/2 cup white sugar
1/2 cup powdered lemonade mix (such as Country Time®)
Bring the water to a boil in a large pot, and stir in the tea bags, raspberries, and sugar until the sugar has dissolved. Allow the mixture to steep until the desired level of tea flavor is reached, 3 to 5 minutes; remove tea bags, and stir in the lemonade mix until dissolved. Pour tea into pitchers, and add ice to cool.
