Start by placing a pinch of baking soda into a large heat-proof pitcher. This small ingredient helps create a smoother flavor and reduces any bitterness from the tea. Make sure the pitcher can safely handle hot liquids.
Pour the boiling water into the pitcher and immediately add the tea bags. Cover the pitcher and allow the tea bags to steep for about 15 minutes. This gives the tea enough time to develop a rich flavor without becoming overly strong.
Once the steeping time is complete, carefully remove the tea bags and discard them. Avoid squeezing the tea bags because this can release extra tannins and create bitterness in the finished tea.
Add the sugar while the tea is still warm. Stir continuously until every bit of sugar has completely dissolved. This step ensures the sweetness is evenly distributed throughout the tea.
Pour the cool water into the pitcher and stir well. The additional water balances the concentrated tea and creates the perfect drinking strength.
Transfer the pitcher to the refrigerator and allow it to chill completely. Cold sweet tea tastes smoother and more refreshing, making it perfect for hot weather.
Once chilled, pour the sweet tea over ice-filled glasses. Garnish with lemon slices or fresh mint if desired. Serve immediately and enjoy every refreshing sip.
