Wash and peel
Cut into six pieces
Treat the heart core and soak it in salt water.
Then steam on the pot for eight minutes.
After steaming, put it in the oven and bake it up and down for 120 hours. Then take it out and steam it. Then I will bake it for another hour at 90 degrees and then turn it to 60 degrees and bake it several times.
Baked to a personal taste, you can make a very delicious apple tart.
