This hot mustard sauce is a fantastic accompaniment to ham, corned beef, grilled chicken, and a juicy steak — use it in place of your favourite table mustard. The feisty, hot kick of the mustard is tempered by the acidity – for a less tangy mustard sauce you can substitute the white wine vinegar for an equal portion of the corned beef cooking water.

- ½ cup white wine vinegar
