Recipe: Storage time for dry mustard and some info about storing prepared mustard

Hi Marilyn, Here's some info for you...

According to this handy spices storage chart at Eatbydate.com:

Mustard (the spice) lasts for:
Ground: 2-3 years
Dried: 2-3 years
Whole: 4-5 years

Here's some interesting info I ran across that I didn't know about prepared mustard:

Storage and shelf life for mustard:
"Prepared mustard is sold at retail in glass jars, plastic bottles, or metal squeeze tubes. Because of its antibacterial properties, mustard does not require refrigeration; it will not grow mold, mildew, or harmful bacteria. Unrefrigerated mustard will lose pungency more quickly, and should be stored in a tightly sealed, sterilized container in a cool, dark place. Mustard can last indefinitely, though it may dry out, lose flavor, or brown from oxidation. Mixing in a small amount of wine or vinegar will often revitalize dried out mustard. Some types of prepared mustard stored for a long time may separate, which can be corrected by stirring or shaking. If stored for a long time, unrefrigerated mustard can acquire a bitter taste." - From: Wikipedia

Happy Cooking!
