I was wondering how long piping gel stays good refrigerated?
It doesn't need to be refrigerated. It last a long, long time at room temp.
Wow really....like months?
If you search online, you'll find answers that say up to 1 year.
If you search here, you'll find answers claiming up to 5 years. (I believe YEARS is appropriate since you'll find answers that corn syrup has a shelf life for between several years to indefinitely in the pantry.):
