10 cups water

4 large tea bags (Lipton or Luzianne or Twinings)

1/8 teaspoon baking soda

1 lemon, sliced

In a large saucepan bring 5 cups of water to a boil.  Remove from heat and stir in baking soda.  Add tea bags and let steep for 15 minutes.

Remove tea bags, but DO NOT squeeze-it will make it bitter.

Pour concentrated tea into a large pitcher and add the remaining 5 cups of water.  Pour over ice and add a slice of lemon.
