Grapefruit candy is highly sensitive?

Although the memory is fading away, the sweetness of grapefruit sugar has already penetrated into the bone marrow. In my memory, every year when grapefruit is ripe, my mother likes to do one thing and collect grapefruit skins everywhere. Mother took the collected grapefruit peel, removed the yellow peel on the surface, chopped up the remaining pulp, put it in a pot, and boiled it with water and appropriate amount of rock sugar. In order not to let the sticky grapefruit peel juice paste the pot, mother kept stirring with a spatula. Mother will put the cooked mushy grapefruit candy into a beautiful blue and white porcelain jar. Grapefruit candy has a little astringency of grapefruit peel, and more is the sweetness of rock sugar. I think it's the most beautiful taste in the world.
