You can wash Sydney with or without peeling, but remove the pear core to avoid the sour taste of the boiled pear water. Cut the processed pear into hob blocks, add a proper amount of water into the pot, add rock sugar when it is almost boiling, heat it with low fire until the rock sugar melts, put the pear blocks in after the rock sugar melts, boil it with high fire, and then cook it with low fire for about 15 minutes, and a delicious rock sugar Sydney is made.

Sydney tastes sweet and cold, and contains malic acid, citric acid, vitamin B 1, vitamin B2, vitamin C, carotene, etc. It has the effects of promoting fluid production and moistening dryness, clearing away heat and resolving phlegm, and also has the effects of relieving cough and moistening dryness. The taste of Sydney is more delicious after adding rock sugar.
