English mustard (not Colmans) -- help!
I spent 6 months at QMUL in London, and in one of the cafeterias there, they had little packets of mustard available, of which I cannot remember the name. The mustard was lighter in color than Colmans (not at yellow) and significantly hotter. Can anyone help me name this mystery mustard? I would like to purchase it, but I don't know the name!
