One pint of yellow English mustard flour, half a pint of white granulated sugar, one gill of fine salt, one gill of cider vinegar. Put the mustard flour into a porcelain bowl and pour in slowly boiling water enough to make it into a dough, stir it until it is all scalded and perfectly smooth. Then stir in the sugar and mix it well together, then add the salt and last the vinegar, mix it well together, then put it into small, wide mouthed glass jars, and cork it tight, it will keep good a long time. It is very fine for the castor and for salad dressing.
