Step‑by‑Step Instructions for Petri Dish Jello Shots

Step 1: Boil the Water
Start by bringing 1 ½ cups of water to a rolling boil in a medium-sized saucepan over high heat. Make sure to watch for bubbles forming vigorously, signaling that your water is ready. This step is crucial as the boiling water helps to fully dissolve the lime jello powder for a smooth texture in your Petri Dish Jello Shots.

Step 2: Dissolve the Jello
Once the water reaches a boil, carefully pour it into a large mixing bowl containing the lime jello powder. Stir the mixture continuously for about 2 minutes until all the granules have completely dissolved. You’ll know it’s done when the mixture appears clear without any visible specks, ensuring a beautiful finish for your jello shots.

Step 3: Add the Fizz and Kick
After the jello is fully dissolved, gently mix in 1 cup of chilled lemon-lime soda and ½ cup of tequila (or vodka if you prefer). Stir this combination briefly, avoiding excessive agitation to keep the fizz intact. If you'd like a sparkling twist, you can sprinkle in some edible glitter at this stage for an eye-catching shimmer in your Petri Dish Jello Shots.

Step 4: Fill the Dishes
Carefully pour the jello mixture into clean petri dishes or small cups, filling them to the desired level. Aim for about three-quarters full to allow space for the jello to set properly. As you pour, take care to minimize spillage, creating a neat and appealing display that enhances the playful lab-themed aesthetic of the jello shots.

Step 5: Chill Until Firm
Refrigerate the filled petri dishes for at least 3 to 4 hours, or until the jello has fully set. You’ll know they’re ready when you can gently wiggle them and see that they hold their shape firmly. Cover them loosely with plastic wrap to prevent fridge odors from seeping in, ensuring your Petri Dish Jello Shots stay fresh and delightful.

Step 6: Garnish & Serve
Once the jello shots are set, take them out of the fridge and garnish with candy eyeballs right before serving for a fun and festive touch. Arrange them on a platter for an enticing presentation that will delight your guests. These playful Petri Dish Jello Shots not only taste great but also create a memorable visual impact at any gathering.

Make Ahead Options

These Petri Dish Jello Shots are perfect for meal prep enthusiasts looking to save time for their next gathering! You can prepare the jello mixture up to 24 hours in advance; just follow the initial steps of dissolving the lime jello in boiling water, adding the lemon-lime soda, and tequila. Pour the mixture into the petri dishes, then cover them loosely to prevent fridge odors and maintain that delightful flavor. Refrigerate them until set for 3-4 hours before your event. Right before serving, simply garnish with candy eyeballs to keep them looking fresh and appetizing. With these easy make-ahead tips, your party prep just got a lot simpler, ensuring delicious Petri Dish Jello Shots while freeing up your time for hosting!

Absolutely! When making Petri Dish Jello Shots, check for any dietary restrictions among your guests.
