Gravy
OXO is a stock and seasoning agent, gravy is the end-product that comes from using OXO (among other things)
I prefer the traditional method of making gravy personally, using 'proper stock', but most people don't bother now
Anyone remember 'gravy browning'? Also used as a 'fake tan' after the war apparently
Probably worked great, until it rained
Edit: 'Fake Tan' & 'Stockings'
