Yam ribs soup

Ingredients: yam, sparerib, onion, ginger, salt and yellow wine. Practice: wash yam, peel and cut it off, and steam for 2 minutes. Wash the ribs, fill the casserole with water, boil, and skim off the floating foam. Add ginger slices and onion knots, add yellow wine, turn to low heat, simmer for one hour, pick up onion knots, put yam, and turn to low heat after boiling over medium heat. After half an hour, add a proper amount of salt and continue to simmer for half an hour until the yam ribs are crisp and rotten. CCOTS Food Tips: After the yam is steamed, the greasy juice can be removed, so that the boiled soup is clearer.
