Plum sauce is a sweet and tangy condiment typically made from plums, sugar, vinegar, and various spices like ginger, garlic, and sometimes chili. It has a thick, glossy texture and is often used in Chinese cuisine, particularly with dishes like Peking duck, spring rolls, and grilled meats. The sauce’s flavor profile is a balance of sweetness and acidity, with a hint of umami from the added seasonings. It’s popular in both cooking and as a dipping sauce. It is ideal for marinating, dipping and dressing.
