Sour plum soup, a beloved Chinese summer staple, is cherished for its sweet-tart flavor and cooling properties. Making it at home is simple, requiring just a few key ingredients.
Start with 100g dried sour plums (prunus mume) and 30g rock sugar, which balance the sourness with a gentle sweetness. Soak the plums in warm water for 30 minutes until softened, then remove the pits. In a pot, combine the pitted plums, rock sugar, and 1 liter of water, adding a handful of dried osmanthus flowers for an aromatic touch if desired.
Bring the mixture to a boil, then reduce heat and simmer for 20–30 minutes until the sugar dissolves and the liquid deepens in color. For a richer taste, some recipes add 10g of dried tangerine peel or a pinch of salt to enhance the flavors.
Let the soup cool completely, then strain it to remove the plums and flowers. Serve chilled over ice for a refreshing drink. This traditional beverage not only quenches thirst but aids digestion, making it a perfect homemade treat for hot days. The blend of sourness, sweetness, and floral notes embodies the essence of classic Chinese culinary wisdom.
