how long do jello shots take to set

Jello shots typically take about 2 to 4 hours to set in the fridge, with larger or more alcohol-heavy batches leaning toward the longer end. For best results, plan for at least 4 hours, and many people find overnight chilling ensures they’re fully firm when served. If you’re in a rush, you can speed up the process slightly by using smaller cups (around 2-ounce portions) and ensuring the fridge is cold enough, but the conventional guidance is to aim for 4 hours or more.
