Authentic ebony soup tastes very appetizing, so what is the recipe for authentic ebony soup?

Put black plum, hawthorn, licorice and tangerine peel in a drain basket, rinse away the dust with clean water, and soak in clean water for 10 minutes. After the tangerine peel is soaked, take it out, use a knife to scrape off the orange peel, which is the white layer inside the tangerine peel, and cut it into shreds. Pour out the soaked plums, hawthorns and licorice and drain the water. Pour appropriate amount of water into the pot. Add black plum, hawthorn, licorice and tangerine peel, cover the pot and soak for 20 minutes. Turn up the heat, bring to a boil, then reduce the heat to medium and simmer for 40 minutes. Add appropriate amount of rock sugar. Cook until the sugar dissolves.

Or prepare ingredients: 3 ebony plums, 25g hawthorn, 20g tangerine peel. Rinse the tangerine peel with clean water and soak the dried hawthorn with water. Rinse the ebony plums with clean water. The taste of ebony plums will be a little sour. If you give it to your baby, it is best to soak it in water for a while to remove part of the sour taste. Drain the water from the ingredients, put them into the pot, and add appropriate amount of water. The soaked water will turn a little yellow, bring to a boil over high heat. After the water boils, add an appropriate amount of rock sugar, turn to low heat and simmer for 1 hour and 30 minutes. After cooking the plum soup, use a strainer to filter out the ingredients and residue.
