Mustard powder is often added to salad dressing recipes, to help blend oil and vinegar, and to add a spicy zip. When adding mustard to baked goods, remember that it will inhibit yeast growth, thereby increasing the rising period.

Mustard comes from the same family as horseradish and it is the compounds common to both spices that give them their heat.

Mustard powder is a great way to add heat to a dry rub without the lingering intensity that you get from chili peppers. Mustard powder brings a distinctive tanginess to grilled meats that enhances both the flavors of meat and those of the other spices used to season it. It works on meats like chicken, beef, and pork.

Mustard powder is a great addition to vinaigrettes where it works as an emulsifier to aid the blending of oil and vinegar. Great addition to a mayonnaise as well. Mustard powder brings the mustard flavor without the addition of moisture; prevents your coleslaws and potato salads from becoming watery.

You can make your own prepared mustard by combining mustard powder with a sweetener, vinegar, and water to get the desired consistency. Some recipes use wine as the liquid.
