Dry Mustard Shelf Life

I have a tin of dry mustard ... probably at least 3 yrs. old, that is rarely used. I need about two teaspoons for my turkey breast and wonder if it is too old. Does it lose it's flavor like wet mustard?

  1. Not noticied any problem. The tin we currently have has a "best before" date of 2009 and it still seems fine.

    1. The best way to tell is to taste it. So many factors can impact how long a spice is good for, not just the age of item.

      If you can’t bear to taste the dried mustard by itself you can mix w/ a little mayo and dip a pretzel in it or put on sandwich. With

      1. Oh, goodness, mine is 11 years past its expiration date. I never use it, the kids used to use it, and left it here in the top of my cabinet. My brother wants it, but I need to know if its OK or not. Probably better toss it, and buy some new.

          Not going to kill you but will not have the same bite. Will not have a good flavor at all, toss it. I do buy it in big plastic bottles but the tins do seem to keep it better.

            It will lose some potency but, is fine. That will last long past our departure.

          2. Thanks to all of you ... I hate throwing out spices... even when the tins get old enough to walk to the garbage can by themselves.

              Thank you all for the answers, my brother took one look at the tin, and said he would drive all the way to the store, 7 miles, to get some new.
              I think that I shall go thru my spices and take a look at my dates on them, and replace any that are really old or icky.
              I try to write the date of purchase on everything we buy that we know that won't get used up right away.
