Boil 1 liter of black tea and let it steep. Meanwhile, heat the liter of apple juice in a large saucepan. Add the tea and continue heating. Cut the lemon into slices and add with the cloves and cinnamon sticks and let it steep (about 15 minutes). Finally, add sweetener to taste.
Tastes great at any occasion!
A little tip: especially tasty with a dash of amaretto!
