Notice the blob of English mustard? Essential for roast-beef. Or can you find horse-radishes
growing in China?

Any mustard is OK as far as I am concerned. Of course. 'Coleman's' is the best by far, but who really cares?
Roast beef and Pork Pies always SCREAM for mustard in my opinion, however, I can eat mustard with bacon and eggs at breakfast time, lol.
