Brown sugar Jiang Shui needs brown sugar and ginger. When cooking, it is usually cooked with slow fire for 5- 10 minutes, because the cooking time of ginger should not be too long, otherwise the gingerol component in ginger will be volatilized when heated, which will weaken the efficacy of ginger slices. At the same time, the boiling time should not be too short, so as not to affect the taste of brown sugar Jiang Shui due to the spicy taste caused by uncooked ginger. Drinking some brown sugar Jiang Shui in moderation can promote blood circulation, warm the stomach, relieve exterior symptoms and dispel cold, and is suitable for people with stomach cold vomiting and cold.
