1. Brew the Tea:
Bring 4 cups of water to a boil in a saucepan. Remove from heat, add tea bags, and let steep for 10 minutes. Remove tea bags and stir in baking soda if using.

2. Make the Strawberry Syrup:
In another saucepan, combine sliced strawberries, 2 cups of water, and sugar. Bring to a boil, then reduce heat and simmer for 10 minutes. Mash strawberries gently and strain through a fine mesh sieve to remove pulp and seeds.

3. Combine:
In a large pitcher, combine brewed tea and strawberry syrup. Stir well, then refrigerate until chilled.

4. Serve:
Serve over ice and garnish with fresh mint and strawberry slices if desired. Enjoy cold and refreshing!
