Tender lamb is simmered with angelica root and warming herbs in a nourishing medicinal broth. This high protein family tonic soup is a traditional Chinese winter remedy for boosting circulation and vitality.
Rinse the lamb shoulder thoroughly, then cut into large chunks; blanch in boiling water for 2 minutes to remove impurities, then drain.
In a large stockpot, combine the lamb, angelica root, ginger, and water. Bring to a vigorous boil over high heat, then reduce to low and skim any foam.
Cover the pot; simmer gently on low heat for 90 minutes, making sure the broth never boils aggressively to preserve delicate flavors and prevent toughening the lamb.
Add red dates and goji berries; continue simmering on low for another 30 minutes, allowing herbs to infuse fully while keeping the lid cracked for steam to escape.
Season with salt and white pepper, stir well and let rest for 10 minutes off-heat before serving so flavors meld and the soup clarifies.
