This condiment is made from the seeds of the mustard plant. There are black, brown, yellow and white mustard, each with a different pungency. The seeds are sold whole or in powder form (ground seeds). Manufactured mustard powder is usually a mixture of one or more varieties of mustard seed. There are various types of mustards: English mustard, French mustard (eg. Dijon), German mustard and others that are made from the alba seeds and flavoured with sugar, vinegar and white wine (the one that goes over your hotdog or hamburger).
Use: As a condiment or to thicken sauces. The powder form can be used in sauces, marinades, flavouring dishes, salad dressings, gravies, while the seeds can be used for pickling and seasoning. And delicious with roast beef.
