Stranger: heey
You: Melt the butter in a heavy pan and cook the onion on the hob for 20 minutes, stirring frequently until soft
Turn the heat down low, do not cover the pan and cook until the onions are brown, this should take around 1 hour or more, dont rush it, leave them cooking and read the paper! The long, slow cooking gives the depth of taste and colour to the gravy
Add the stock and if using the booze, Worcestershire sauce and mustard
Bring the gravy to the simmer, stir frequently, check the seasoning and serve
