In a heat resistant large measuring cup (I use a 4 cup measuring cup), add the Lipton Black Tea bags and sugar, then pour over with freshly boiled water. Add a pinch of baking soda. Allow to brew for about 5 - 8 minutes. This will make your 1 pint of concentrate.
In a large 2 quart pitcher, first add the ice until about 1/2 to 3/4 full. If using a glass pitcher, don't forget the metal spoon to keep your glass from cracking.
Slowly pour the tea concentrate over the ice.
Add in the lemon and orange slices, plus the mint if using.
Top up with more cold, filtered water.
Serve over ice and enjoy.
