Bao Ding Soru 500ml, an essential ingredient in Shanghai cuisine, is a magical seasoning made from sweet and sour vegetable residue, which is used to marinate ingredients and dramatically improve their flavor. It also contains live fermentation yeast to promote fermentation, and is fermented at low temperatures to maintain freshness. You can enjoy the rich aroma and richness that only Soru can provide. After cooking the seafood and vegetables, arrange the ingredients in a Tupperware or enamel container, fill it with Soru, and marinate for about half a day, and they are ready to eat.
