Step 1: Heat the pan first, then pour in a little cooking oil and turn it over for a while, so that the pan will be full of oil.

Step 2: When the oil temperature gets hot, pour in rock sugar or white sugar and quickly break the rock sugar to prevent fire.

Step 3: Wait until the rock sugar is completely broken, then turn to medium heat and continue to stir the rock sugar to make it completely liquid. If the heat is not well mastered, you can also use a small fire when frying the sugar color, but this will be slower.

Step 4: When the sugar becomes liquid, turn off the gas stove to the minimum fire and continue to stir-fry the sugar. When the sugar bubbles, turn off the gas stove and continue to stir-fry the sugar with the remaining temperature of the pot until the sugar turns red. At this time, the sugar is completely fried.

Step 5: Put boiling water equal to sugar in the pot, and stir with a spoon to serve.
