You can not beat a cup of Bovril, with salt and pepper.Used to have it at the Blues.
It can be done but it looks painful..We still drink OXO or Bovril in the wintertime; warming the 'cockles' of our hearts.
As a youngster my chum and I would often get an OXO cube from a grocery store to eat on the way home. I think they were half a penny (old coinage) each.
Warmer days would see is in the Milk Bar having a milk shake. My favourite flavour was pineapple. You can still get the syrup flavourings from wholesalers.
The thing i remember about oxo as a kid in the 40/50s is when money was short we would have a cup of oxo with dry bread it did fill a hole in your tummy
