Mustard, dried

We most often use dried mustard as an ingredient in a vinaigrette Francaise, i.e. when preparing an oil and vinegar dressing destined for a French inspired dish, such as Salade Nicoise. The addition of dried mustard gives the vinaigrette a lovely tang hard to describe. However, use sparingly. Once I got a little carried away with the result a bitter tasting vinaigrette.
