Instead of a recipe, how about a little bit of information today from my favorite reference site.
Fact of the Day: Mustard is a herbaceous plant originating in the Mediterranean. Of the numerous species of mustard, several have edible leaves, some produce edible oil, and a few provide seeds which are used to make the condiment of the same name. The seeds contain myronate and myrosin, which release a volatile and piquant essence when crushed in the presence of water, giving mustard its distinctive flavor. The condiment made from mustard seeds can be flavored with tarragon, garlic, mixed herbs, horseradish, honey, chili, paprika, or fruit.
