1. Cut grapefruit peel into strips
2. Put some salt in a larger container
3. Add water to soak for 30 minutes
4. Take out the squeezed-dry water, and then wash it with clean water several times to squeeze the water (this can remove half of the bitterness)
5. Put the rock sugar in the pot and add a small bowl of water to boil it into sugar water
6. Add the squeezed grapefruit peel and cook on a low heat until transparent
7. Cook until the water is dry and the sugar water is completely absorbed by the grapefruit peel
8. Pour into the baking dish
9. Put it in the oven and bake at 100 degrees for 1 hour until it is completely dry
10. Well done is not only not bitter but also delicious
Tips:Although the grapefruit peel is particularly bitter, it can be relieved with more bubbles. Add enough sugar water to cook it without any bitterness. The finished grapefruit peel can be placed in a cool place for a winter.
