From Cantonese friends and Hongkong I learned about Honey Lemon tea (or Lemon Honey tea). It tastes like ice tea, but hot and there is no tea used. You can also drink it cold, then it tastes like ice tea.xD
It’s quite simple to make:
You can make a big honey/lemon pot and enjoy it for a long time. You might need to remove some honey or get a bigger pot when you are adding the lemon slices. Wash the lemon before cutting, since the skin will also be used.
At work I have a small pot with lemon slices and a squeeze honey tube for more sweetness. Delicious and good for you when you have a sore throat.
