If you want to blend, heat the rapeseed oil, not the fire.
Wash the pan and heat it. Then the oil ratio is similar to sugar, but it can be a little more. The oil temperature is around 60%.
How to measure the oil temperature? We often cook, and we know at a glance that no one can.
Great, just put your hand at a distance from the pot and feel it with your hand.
Add sugar when the oil temperature is enough, and then stir-fry until the sugar feels mushy, and then leave the pot and the fire, but be careful not to turn off the fire at this time because the temperature will be very different when it is turned on and off, so stir-fry.
The effect is not good. Just stir-fry until the sugar turns red and sticky as above.
However, it is mentioned here that it is also good to stir in the pot with a spoon when frying.
This method of boiling sugar should be used in shredded apples, shredded yam and other dishes.
