Start by boiling a quart of water in a kettle. Avoid heating the water to boiling point or for more than 5 minutes.

Add tea bags to the pitcher and pour the warm water over them. Steep green and black tea for 3 minutes at the most. Any more will make your tea bitter. If you prefer honey bush tea, you can steep for 5-8 minutes.

Remove the teabags, close the pitcher and place it in the sun. The place you choose should at least have 3 hours of direct, uninterrupted sunlight. Allow it to warm up or chill in the fridge; garnish with lemon wedges if desired and serve.
