2. Cut the chestnuts and put them into the pressure cooker, then put a spoonful of oil and a spoonful of sugar, turn on medium heat, stir fry, put your hands on the pressure cooker, and cover the pressure cooker when you feel hot, without adding a valve, and use medium and small heat.
3. Shake the pressure cooker gently with the handle of the pressure cooker, let the chestnuts roll in the pot for about 5 seconds, and stop for half a minute. After a while, the fragrance of chestnuts will float out, and the frequency of shaking can be less, and the frequency of shaking will be higher in the future. Stir until you hear chestnuts crack, and then continue stirring for one or two minutes.
4. Pour out chestnuts while they are hot. Don't put them in the pot. It is best to put it in a breathable container, otherwise the condensed water will affect the taste of chestnuts.
