Salt if necessary Lemon wedges,optional Saute onions and carrot in corn oil in the bottom of a 5 litre soup kettle,until softened,about 10 minutes.Combine with remaining ingredients, (except lemon wedges)and simmer over low heat,covered,but with lid askew for 50 minutes.Taste for salt and serve in hot bowls.Serve with lemon wedges if desired....This is not my favorite cabbage soup...
