Query: Good Old Marmite!

When we were kids we ate it a lot - its versatile, concentrated and a tasty flavoring. Very good on toast with butter and a cup of tea. But, the big deal was if we got a chill or didn't feel well, Marmite always did the trick. A little dab mixed into a cup of hot water makes a delicious instant healing broth to sip on. It works like magic for a head cold!
