Add blueberries, honey or sugar, water, and lemon juice to a small saucepan. On medium heat, bring to a simmer. Stir consistently, meanwhile using the spoon (you might also find a potato masher helpful) to crush the blueberries. Once sugar has fully dissolved and blueberries are all crushed, reduce the heat to low and simmer for 10 minutes. Strain.
Make Blueberry Iced Tea

Remove from the heat and add tea. Steep for five minutes. Strain. Mix in blueberry simple syrup and remaining 3 cups water. Pour into a 68-72 ounce pitcher filled with 1 cup ice. Serve/pour over additional ice in glasses.
Notes
