Andrew Wynter, Once a Week (1860)
“ That prime ‘Durham Mustard,’ for instance, is a delusion and a snare. There’s scarcely a bit of mustard that you can get pure at any price. This stuff is nothing more than 95 per cent. of wheaten-flour, just a dash of pure mustard, turmeric to paint it up to concert pitch, and black pepper to make it sting; and you have been labouring under the delusion all the while that you have been eating mustard, sir. ”
