Ingredients:
- 4 cups filtered water
- 12 standard-size black tea bags
- 0.25 teaspoon baking soda
- 1.75 cups granulated white sugar
- 12 cups cold filtered water
Instructions:
- Bring 4 cups of filtered water to a rolling boil in a large stockpot.
- Remove the pot from the heat. Submerge the tea bags and add the baking soda. Steep for exactly 15 minutes.
- Remove the tea bags carefully with a slotted spoon. Do not squeeze the bags to prevent releasing bitter tannins into the tea.
- Add the granulated sugar to the hot tea concentrate. Stir vigorously until the sugar is completely dissolved.
- Pour the concentrate into a 1-gallon glass pitcher and add the remaining 12 cups of cold filtered water. Stir well.
- Allow the tea to cool at room temperature for 30 minutes, then refrigerate for at least 2 hours to chill.
- Serve in glasses filled to the brim with ice, garnished with lemon or mint if desired.
