Hi Dch48,
Bangers and mash with friend onions. The word bangers comes from the days of WWII when sausages came so full of water that they went bang. To prick them with a fork would prevent that explosion. That is why they were called bangers as sausages were filled in sheepskin that would explode with a loud bang when cooked and fried long enough. What the Banger Sisters had to do with it, is still a bit unclear to me, but I add that information for folks for which the sixties never seem to end,

P.S.
@DavidR, with bratwurst also the mustard is different. English mustard is among the strongest around.
