When we were ill as kids, we were given beef tea, made using Marmite (or OXO or Bovril or Bovo or Vegemite..... any of the above). A nice lite savoury hot drink, especially good when you can't face anything sweet. These days I always start the day with a concoction made from 1/2 teaspoon Teaco Beef Tea (Bovril is OK but 3x the price), 1/2 teaspoon plain gelatine and when that's dissolved in 3/4 cup of hot water, throw in about 1 dessertspoonful of flaked yeast. It keeps my old bones lubricated, gives me lots of B vitamins and sets me up for the day!
