Peel the carrots and cut the slices of the same thickness;
Pour carrots and rock sugar into the pot and add 200 grams of water.
Boil the fire, change the medium heat to boil the water, let the carrots fully absorb the sugar, about 25-35 minutes;
Remove the carrots and drain the water completely with a colander;
Spread the carrot slices on the baking sheet and enter the middle layer of the oven for 120 minutes and 90 minutes.
Because it takes a little time to drain the water, I completed the previous steps the night before, and the oven was the next morning.
