I'm living in a really hot climate, and i was wondering if it's ok to keep wilton gel colors outside, or should i store them in the refrigerator,,, temperature here goes as high as 45 degrees Celsius. Any help will be much appreciated.
They'll be fine as long as you don't cross contaminate the container - in other words introduce anything on the tip of a toothpick or knife from the cake back into the bottle so that bacteria can grow. And keep them out of sunlight. should be fine. If you open a container and smell a strong odor, that's your clue to toss it.
Yah, what she said ^^^^^
I have kept some of them for over 10 yrs now.....always at room temp.
I even have some pre- jel colors - some as much as 50 yrs old!
