Chrysanthemum and Wolfberry Tea

Got this from a Terry Tan book, i think. But i just made the text easier to understand (for me).

Water 1l (cooked)
Rock sugar 20gm
Wolfberries or Kei-zi 10gm
Chrysanthemum 10gm (the best are those wild, small flowers)

Step 1
Combine water and rock sugar, heat until sugar dissolves.
Step 2
When all sugar has been dissolved, remove from heat and put in the rest of the ingredients.
Step 3
Steep for 15 minutes, then strain.

SERVE WARM
