Once mixed, Jell-O remains fresh in the refrigerator for seven to ten days. Unopened vodka, which is frequently used to make Jell-O shots, has an endless shelf life.
If the Jell-O shots change colour or develop an odour, the vodka in them may no longer be fresh. If Jell-O acquires a bitter taste and water begins to accumulate on its sides, it has gone bad and must be destroyed. Jell-O should be prepared and consumed by the “sell by” date on the packaging to assure its safety.
