...does it ever expire? I've got some from last year and I'm baking today-didn't know if I may need to get a fresh box.

  • Put some in a bowl. Add in some vinegar. If it fizzes, it's fine, if it doesn't do anything, time for new.

  • As long as it hasn't picked up any odors from other foods it was stored around, it should be fine.

  • Well I guess I don't need to tell you to try the vinegar test but I will say it does work.

  • Do you have it in the frig? You need to replace it after 30 days if you are using it to keep the frig fresh.

  • It does lose it's effectiveness. Use the vinegar test, as mentioned earlier, and it should really fizz, like it's boiling. If it only fizzes a little, it's really not going to work very well. When you buy a new box, transfer it to an air-tight container to store it in.

  • If you are going out anyway then pick some up and pour that down the sink. It never hurts to have it around for cleaning purposes. If you can't go out before baking then try that vinegar test

  • I'm probably going to seem like a stick in the mud here with my answer but i went and looked at my box and it expires 09/2013. I have a thing for expiration dates with food. ALWAYS CHECKING to be sure. My daughter and i were in Wise Buys grand opening day and found something that was due to expire this month and had alot in stock to sell. CRAZY
