How to Store Jello?

Now that we know how long it can last, we need to know how to store it so it can last longer.

How to Store Jello

Let’s start with the dry mix. This mix is quite similar to Pancake Mix in terms of storage, which means you don’t need anything more than a cool and dark place like the pantry to store it properly. This is according to KraftFoods official website.

Once you open the pack, the moisture will start spoiling the mix. This is why you should seal it tightly with some plastic wrap to keep it safe.

The cups are a different story. You need to know how the manufacture intends to store it. Some jello does stay perfectly fine at room temperature, others are not so much. It depends greatly on the type of cup you have.

However, the general rule of thumb is to keep the jello away from the heat sources and sunlight, as these can easily ruin your tasty treat.

If you have homemade cups or cups of jello you bought and opened, consider wrapping them in plastic wrap or put them in an airtight container, as they will preserve the gelatine for much longer and protect it from contamination.

When gelatine freezes, the bond that makes it all wiggly starts to break, and water starts replacing it.

The result? A big mash of iced gelatine will turn into a messy puddle once you thaw it, which is nothing like the jello you put In the freezer.

Another spoilage sign is the separation. Jello is supposed to be holding itself together as this a sign that the gelatine is still intact, once you notice separation, it means that the bonds have broken down and are spoiling, a pool of water on top of your cup should be enough to encourage you to throw it all away.


Strawberry jello should smell like strawberry, not sour and off. If you notice any weird smell, trust your senses, and throw that cup away.
