Pig's Trotters in Vinegar is a heritage must-have Cantonese dish for postnatal mums during the 'confinement period'. The dish is believed to help replenish collagen, warm the womb and purge the "wind" generated during childbirth. The gelatinous pig trotters in sweet black vinegar is a highly appetising and mouthwatering dish enjoyed by many people (non-postnatal-mums included)!
