After creating the rainbow Jello cups, there was quite a bit of leftover Jello. Not wanting to waste a single bit, it was a great opportunity to experiment with stained-glass Jello.

Recipe Notes and FAQ

Why is my Jello watery?

Watery Jello usually results from covering the Jello before it has cooled completely and set. Covering the Jello allows liquid from condensation to drip down into the mix, causing it to have too much water to set properly.

Should you grease a Jello mold?

This recipe uses a simple glass dish, so no greasing is required. For molds that have edges and other fancy contours, spray the mold with a non-stick spray to keep it from getting stuck in the crevices.

How long does Jello last?

Jello will stay fresh for 7 to 10 days when covered and refrigerated.

Does boxed Jello go bad?

Unopened dry Jello mix has an indefinite shelf life when stored at room temperature. However, if the package has been opened, the mix will only last for about 3 months. Check the box for a “best buy” date and try to use it by then for best results.
